net: cadence_gem: Clean up variable names

Cleanup some variable names in preparation for migrating the state
struct and type cast macro to a public header. The acronym "GEM" on
its own is not specific enough to be used in a more global namespace
so preface with "cadence". Fix the capitalisation of "gem" in the
state type while touching the typename. Also preface the GEM_MAXREG
macro as this will need to migrate to public header.
