Now that all the pieces are in place we can start using the A-TCAM
instead of only using the C-TCAM. This allows for much higher scale and
better performance (to be improved further by follow-up patch sets).
Perform the integration with the A-TCAM and the eRP core by reverting
the changes introduced by "mlxsw: spectrum_acl: Enable C-TCAM only mode
in eRP core" and add calls from the C-TCAM code into the eRP core.

Each TCAM region currently uses its own resources and there is no
sharing between the different regions.
This is going to change with A-TCAM as each region will need to allocate
an eRP table from the global eRP tables array.
Make the global TCAM resources available to each region by passing the
TCAM private data to the region initialization routine.

In Spectrum-2, ACL regions that use 8 or 12 key blocks require several
consecutive hardware regions.
In order to allow defragmentation, the device stores a mapping from a
logical region ID to an hardware region ID, which is similar to the page
table that is used to translate virtual addresses to physical addresses.
Add the region association callback to the region create sequence and
implement it as a NOP in Spectrum which does not require it.

For Spectrum-2, we need to insert priority to C-TCAM because HW
needs that info in order to correctly process scenarios where rules
are in both C-TCAM and A-TCAM.
So extend the mlxsw_sp_acl_ctcam_entry_add() args to accept indication
if priority needs to be filled up and implement the priority
computation and fill-up.

This is going to be needed for Spectrum-2 C-TCAM implementation.

Add ops to be called on driver instance init and fini.
This is needed in order to be possible to do Spectrum-2 specific init
and fini work.

To allow easy and clean Spectrum-2 implementation for things that differ
from Spectrum, split the existing ACL TCAM code 3 ways:
1) common code that calls Spectrum/Spectrum-2 specific ops
2) Spectrum ops implementations
3) common C-TCAM code that is going to be shared between Spectrum and
Spectrum-2 implementations
