Add support for lan969x SERDES driver. Lan969x has ten 10G SERDES'es
which share the same features and data rates as the Sparx5 SERDES'es.

In preparation for lan969x, add a way to branch out on code that is to
be executed on either Sparx5 or lan969x. Initially, this is required to
branch out when checking the SERDES types and SERDES speeds, since the
handling of these differ on the two platforms. This will also be used by
the lan969x driver introduced in a subsequent patch.

The register macros are used to read and write to the SERDES registers.
The registers are largely the same on Sparx5 and lan969x, however some
register target sizes differ. Therefore we introduce a new indirection
to the register macros. The target sizes are looked up, using a mapping
table (sparx5_serdes_tsize) that maps the register target to the
register target size.
With this addition, we can reuse all the existing macros for lan969x.
Also the autogenerated macros are now formatted slightly different, to
adhere to a 80 character limit.

The SERDES to CMU mapping is different on Sparx5 and lan969x. Therefore
create a function for getting the CMU index on Sparx5.

We need to handle code differently in a few places. Add a struct:
sparx5_serdes_ops for this purpose, and populate it a with function to
set the SERDES type.

The number of CMU's differ for Sparx5 and lan969x, so add a new field:
cmu_max and use it throughout.

We need to handle a few different constants that differ for Sparx5 and
lan969x. Add a new struct: sparx5_serdes_consts for this purpose. We
populate it with an initial field for the number of SERDES'es: sd_max.

In order to reuse the existing Sparx5 SERDES driver for lan969x, we add
support for private match data, with initial fields for the iomap and
imap_size.
