Patch 1 had a request to change the formatting of it; I have not done
so as I believe a patch should do one change and one change only -
reformatting it is a separate change that should be in its own patch.
However, as patch 2 gets rid of the reason for reformatting it, it
would be pointless, and pure noise to include such an intermediary
patch.
Instead, I have swapped the order of patches 2 and 3 from the RFC

mlxsw: Spectrum-4 preparations
The Spectrum-4 ASIC will support more than 256 ports, unlike existing
ASICs. As such, various device registers were extended with two
additional bits to encode a 10 bit local port. In some cases, new
(Version 2) registers were introduced.
This patchset prepares mlxsw for Spectrum-4 support by encoding local
port in a 'u16' instead of a 'u8' and by extending the definitions of
the various registers to support the extended local port form.

As preparation for the next ASIC, which will support more than 256

It is not possible to use 10 consecutive bits in all registers, and
therefore, the field is split into 2 fields:
1. local_port - the existing 8 bits, represent LSB of the extended
field.
2. lp_msb - extra 2 bits, represent MSB of the extended field.
To avoid complex programming when reading/writing local_port, add a
dedicated macro which creates get and set functions which handle both parts
