The ocelot hardware library shouldn't contain too much net_device
specific code, since it is shared with DSA which abstracts that
structure away. So much as much of this code as possible into the
mscc_ocelot driver and outside of the common library.
We're making an exception for MDB and LAG code. That is not yet exported
to DSA, but when it will, most of the code that's already in ocelot.c
will remain there. So, there's no point in moving code to ocelot_net.c
just to move it back later.
We could have moved all net_device code to ocelot_vsc7514.c directly,
but let's operate under the assumption that if a new switchdev ocelot
driver gets added, it'll define its SoC-specific stuff in a new
ocelot_vsc*.c file and it'll reuse the rest of the code.

This patch is a trivial passthrough towards the ocelot library, which
support port policers since commit 2c1d029a017f ("net: mscc: ocelot:
Implement port policers via tc command").
Some data structure conversion between the DSA core and the Ocelot
library is necessary, for policer parameters.

Ocelot has 384 policers that can be allocated to ingress ports,
QoS classes per port, and VCAP IS2 entries. ocelot_police.c
supports to set policers which can be allocated to police action
of VCAP IS2. We allocate policers from maximum pol_id, and
decrease the pol_id when add a new vcap_is2 entry which is
police action.

The ocelot_port structure has a net_device embedded in it, which makes
it unsuitable for leaving it in the driver implementation functions.
Leave ocelot_flower.c untouched. In that file, ocelot_port is used as an
interface to the tc shared blocks. That will be addressed in the next
patch.

Hardware offload of matchall classifier and police action are now
supported via the tc command.
Supported police parameters are: rate and burst.
Example:
Add:
tc qdisc add dev eth3 handle ffff: ingress
tc filter add dev eth3 parent ffff: prio 1 handle 2 \
matchall skip_sw \
action police rate 100Mbit burst 10000
Show:
tc -s -d qdisc show dev eth3
tc -s -d filter show dev eth3 ingress
Delete:
tc filter del dev eth3 parent ffff: prio 1
tc qdisc del dev eth3 handle ffff: ingress
