net: dsa: lantiq_gswip: store switch API version in priv

Store the switch API version in struct gswip_priv. As the hardware has
the 'major/minor' version bytes in the wrong order preventing numerical
comparisons the version to be stored in gswip_priv is constructed in
such a way that the REV field is the most significant byte and the MOD
field the least significant byte. Also provide a conveniance macro to
allow comparing the stored version of the hardware against the already
defined GSWIP_VERSION_* macros.

This is done in order to prepare supporting newer features such as 4096
VLANs and per-port configurable learning which are only available
starting from specific hardware versions.
