Merge branch 'HW-support-for-VCAP-IS1-and-ES0-in-mscc_ocelot' 

Vladimir Oltean says:

====================
HW support for VCAP IS1 and ES0 in mscc_ocelot

The patches from RFC series "Offload tc-flower to mscc_ocelot switch
using VCAP chains" have been split into 2:
https://patchwork.ozlabs.org/project/netdev/list/?series=204810&state=*

This is the boring part, that deals with the prerequisites, and not with
tc-flower integration. Apart from the initialization of some hardware
blocks, which at this point still don't do anything, no new
functionality is introduced.

- Key and action field offsets are defined for the supported switches.
- VCAP properties are added to the driver for the new TCAM blocks. But
  instead of adding them manually as was done for IS2, which is error
  prone, the driver is refactored to read these parameters from
  hardware, which is possible.
- Some improvements regarding the processing of struct ocelot_vcap_filter.
- Extending the code to be compatible with full and quarter keys.

This series was tested, along with other patches not yet submitted, on
the Felix and Seville switches.

*
* What VCAP_CONST_ENTRY_CNT is giving us is the width of one full TCAM

* Important mention: regardless of the number of key entries per row
* (and therefore of key size: 1 full key or 2 half keys or 4 quarter
* keys), software always has to configure 4 Type-Group values. For
* example, in the case of 1 full key, the driver needs to set all 4
* Type-Group to be full key.
*
* For this reason, we need to fix up the value that the hardware is
* giving us. We don't actually care about the width of the entry in
* the TCAM. What we care about is the width of the entry in the cache
* registers, which is how we get to interact with it. And since the
* VCAP_ENTRY_DAT cache registers access only the subwords and not the
* Type-Groups, this means we need to subtract the width of the
* Type-Groups when packing and unpacking key entry data in a TCAM row.
