This patch use layer_nr function to get layer number to init plane
When plane init in crtc create,
it use the number of OVL layer to init plane.
That's OVL can read 4 memory address.
For mt2712 third ddp, it use RDMA to read memory.
RDMA can read 1 memory address, so it just init one plane.
For compatibility, this patch use mtk_ddp_comp_layer_nr function
to get layer number from their HW component in ddp for plane init.

Pull timer update from Thomas Gleixner:
"New defines for the compat time* types so they can be shared between
32bit and 64bit builds. Not used yet, but merging them now allows the
actual conversions to be merged through different maintainer trees
without dependencies
We still have compat interfaces for 32bit on 64bit even with the new
2038 safe timespec/val variants because pointer size is different. And
for the old style timespec/val interfaces we need yet another 'compat'
interface for both 32bit native and 32bit on 64bit"

As part of the system call rework for 64-bit time_t, we are restructuring
the way that compat syscalls deal with 32-bit time_t, reusing the
implementation for 32-bit architectures. Christoph Hellwig suggested a
rename of the associated types and interfaces to avoid the confusing usage
of the 'compat' prefix for 32-bit architectures.
To prepare for doing that in linux-4.20, add a set of macros that allows to
convert subsystems separately to the new names and avoids some of the
nastier merge conflicts.

The problem is that iscsi_login_zero_tsih_s1 sets conn->sess early in
iscsi_login_set_conn_values. If the function fails later like when we
alloc the idr it does kfree(sess) and leaves the conn->sess pointer set.
iscsi_login_zero_tsih_s1 then returns -Exyz and we then call
iscsi_target_login_sess_out and access the freed memory.
This patch has iscsi_login_zero_tsih_s1 either completely setup the
session or completely tear it down, so later in
iscsi_target_login_sess_out we can just check for it being set to the
connection.

Add ida_alloc(), ida_alloc_min(), ida_alloc_max(), ida_alloc_range()
and ida_free(). The ida_alloc_max() and ida_alloc_range() functions
differ from ida_simple_get() in that they take an inclusive 'max'
parameter instead of an exclusive 'end' parameter. Callers are about
evenly split whether they'd like inclusive or exclusive parameters and
'max' is easier to document than 'end'.
Change the IDA allocation to first attempt to allocate a bit using
existing memory, and only allocate memory afterwards. Also change the
behaviour of 'min' > INT_MAX from being a BUG() to returning -ENOSPC.
Leave compatibility wrappers in place for ida_simple_get() and
ida_simple_remove() to avoid changing all callers.

get_slot_offset() can be called with a NULL 'parent' argument.
In this case, the calculated value will not be used, but calculating
it is undefined. Rather than fixing the caller (__radix_tree_delete)
to not call get_slot_offset(), make get_slot_offset() robust against
being called with a NULL parent.

Prior to doing compiler feature detection in Kconfig, attempts to build
GCC plugins with Clang would fail the build, much in the same way missing
GCC plugin headers would fail the build. However, now that this logic
has been lifted into Kconfig, add an explicit test for GCC (instead of
duplicating it in the feature-test script).
