net: sparx5: add is_sparx5 macro and use it throughout

Browse source 
We dont want to ops out each time a function needs to do some platform
specifics. In particular we have a few places, where it would be
convenient to just branch out on the platform type. Add the function
is_sparx5() and, initially, use it for:

    - register writes that should only be done on Sparx5 (QSYS_CAL_CTRL,
      CLKGEN_LCPLL1_CORE_CLK).

    - function calls that should only be done on Sparx5
      (ethtool_op_get_ts_info())

    - register writes that are chip-exclusive (MASK_CFG1/2, PGID_CFG1/2,
      these are replicated for n_ports >32 on Sparx5).

The is_sparx5() function simply checks the target chip type, to
determine if this is a Sparx5 SKU or not.
