[target-arm,v2,06/15] net: cadence_gem: Clean up variable names

In preparation for migrating the state struct and type cast macro to a public
header. The acronym "GEM" on it's 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.
