drm/i915: Unify uC variable types to avoid flooding checkpatch.pl

With the code motion mostly done, convert all the uC code away
from uint??_t at once (only a couple dozen variables), so that
reading the checkpatch.pl output should actually pinpoint if
a new uint??_t was accidentally introduced.

v2: - Include intel_uc_fw.h too (Sagar)
