gma registers: Allow to specify an offset for display registers

Certain platforms, namely Bay Trail and Braswell, have the display
engine registers at an offset relative to GTTMMADR base. Apart from
that, the registers are rather similar to the ones on GMCH platforms.

Allow platforms to specify at which offset within GTTMM the display
registers are located. Use zero for all currently-supported platforms.
