With recent ti-sysc driver changes, we can probe most devices with device
tree data only and drop the custom "ti,hwmods" property.
We have already added the related device tree data earlier, and have
already dropped the platform data. But we have been still dynamically
allocating the platform data based on "ti,hwmods" property. With recent
ti-sysc driver changes this is no longer needed.

With recent ti-sysc driver changes, we can probe most devices with device
tree data only and drop the custom "ti,hwmods" property.
Let's drop the legacy platform data and custom "ti,hwmods" property. We
want to do this in a single patch as the "ti,hwmods" property is used to
allocate platform data dynamically that we no longer want to do.

We can now probe cpsw with ti-sysc interconnect driver and dts
data. Let's drop the related platform data and custom ti,hwmods
dts property for am3 and am4.
As we're just dropping data, and the early platform data init
is based on the custom ti,hwmods property, we want to drop both
the platform data and ti,hwmods property in a single patch.

In preparation for dropping legacy platform data and custom ti,hwmods
property, we need to make functional clock available for mdio for the
SoCs so the the mdio driver can find it.
The mdio hardware currently relies on a mdio_hwmod to manage the clock
for omap variants. This is wrong though as there are no separate
sysconfig registers for mdio. All the cpsw related components are just
children of the gmac module.
Note that since mdio is a child of cpsw, just doing pm_runtime_get()
in the mdio driver enables the clock. However, since mdio is also used
by davinci that does not implement runtime PM, let's just add the fck
for now.
Also note that am437x mdio already has a clock, let's update it to
not use the legacy clock naming to unify things further.

We are currently using a wrong register for dcan revision. Although
this is currently only used for detecting the dcan module, let's
fix it to avoid confusion.

The ti,no-idle-on-init and ti,no-reset-on-init flags need to be at
the interconnect target module level for the modules that have it
defined. Otherwise we get the following warnings:
dts flag should be at module level for ti,no-idle-on-init
dts flag should be at module level for ti,no-reset-on-init

There is no CLKSEL for timer12 on dra7 unlike for timer1. This
causes issues on booting the device that Tomi noticed if
DEBUG_SLAB is enabled and the clkctrl clock does not properly
handle non-existing clock. Let's drop the bogus CLKSEL clock,
the clkctrl clock handling gets fixed separately.

AM5 and DRA7 SoC families have different set of modules
in them so the SoC sepecific dtsi files need to be separated.
e.g. Some of the major differences between AM576 and DRA76
DRA76x AM576x
USB3 x
USB4 x
ATL x
VCP x
MLB x
ISS x
PRU-ICSS1 x
PRU-ICSS2 x
This patch only deals with disabling USB3, USB4 and ATL for
AM57 variants.

We need to add mcasp l3 port ranges for mcasp to use a correct l3
data port address for dma. And we're also missing the optional clocks
that we have tagged with HWMOD_OPT_CLKS_NEEDED in omap_hwmod_7xx_data.c.
Note that for reading the module revision register HWMOD_OPT_CLKS_NEEDED
do not seem to be needed. So they could be probably directly managed
only by the mcasp driver, and then we could leave them out for the
interconnect target module.

Hwmod parses the DT hierarchically from root to search for matching
ti,hwmod property. With the introduction of L4 data, we have two nodes
with the ti,hwmod = "gmac" declaration, and the hwmod core only matches
the first one found, which is the target-module one. This node incorrectly
dropped the ti,no-idle flag, which causes number of problems, like ignoring
errata i877, and also causing an intermittent boot failure on certain dra7
boards.
Fix the issue by moving the ti,no-idle flag to the proper node.

With l4 interconnect hierarchy and ti-sysc interconnect target module
data in place, we can simply move all the related child devices to
their proper location and enable probing using ti-sysc.
In general the first child device address range starts at range 0
from the ti-sysc interconnect target so the move involves adjusting
the child device reg properties for that.
In case of any regressions, problem devices can be reverted to probe
with legacy platform data as needed by moving them back and removing
the related interconnect target module node.

Similar to commit 8f42cb7f64c7 ("ARM: dts: omap4: Add l4 interconnect
hierarchy and ti-sysc data"), let's add proper interconnect hierarchy
for l4 interconnect instances with the related ti-sysc interconnect
module data as in Documentation/devicetree/bindings/bus/ti-sysc.txt.
Using ti-sysc driver binding allows us to start dropping legacy platform
data in arch/arm/mach-omap2/omap*hwmod*data.c files later on in favor of
ti-sysc dts data.
This data is generated based on platform data from a booted system
and the interconnect acces protection registers for ranges. To avoid
regressions, we initially validate the device tree provided data
against the existing platform data on boot.
Note that we cannot yet include this file from the SoC dtsi file until
the child devices are moved to their proper locations in the
interconnect hierarchy in the following patch. Otherwise we would have
the each module probed twice.
