Change to ARM's naming convention in DriverDetails.
This matches how ARM handles their naming in their drivers for different models.
Really it's that way because both Mali-T6xx and Mali-T7xx fall under Midgard.
While everything else (except Mali-55) fall under Utgard.
Fix "warning: unused variable 'skipFrames'"
Interpreter: don't PanicAlert on write to SPR_HID2.

The alert apparently triggers on Midway Arcade Treasures 2; given that the
game otherwise works fine, it's not a high priority to accurately emulate
the bit in question.

Fixes issue 7197.
