[PATCH 1/2] drm/xe/guc: Clean up of GuC 'CTL' defines

[John.C.Harrison@Intel.com]

From: John Harrison <John.C.Harrison@Intel.com>

All the field generation for the CTL defines (used for GuC init data)
were hand-rolled rather than using FIELD_PREP/REG_GENMASK/BIT macros.

Also, there were a bunch of macros defined for verbosity settings that
were never used - it's just a number from 0 to 3, why do we need a define
for each level!?

So fix that all up.
