net: dsa: lantiq_gswip: use regmap for register access

This series refactors the lantiq_gswip driver to utilize the regmap API
for register access, replacing the previous approach of open-coding
register operations.

Using regmap paves the way for supporting different busses to access the
switch registers, for example it makes it easier to use an MDIO-based
method required to access the registers of the MaxLinear GSW1xx series
of dedicated switch ICs.

Apart from that, the use of regmap improves readability and
maintainability of the driver by standardizing register access.

When ever possible changes were made using Coccinelle semantic patches,
sometimes adjusting white space and adding line breaks when needed.
The remaining changes which were not done using semantic patches are
small and should be easy to review and verify.
