drivers/intel/gma, soc/intel/common: improve cooperation

Instead of both featuring their own VBT loaders, use a single one.
It's the compression-enabled one from soc/intel/common, but moved to
drivers/intel/gma.

The rationale (besides making all the Kconfig fluff easier) is that
drivers/intel/gma is used in some capacity on all platforms that load a
VBT, while soc/intel/common's VBT code is for use with FSP.

BUG=b:79365806
TEST=GOOGLE_FALCO and GOOGLE_CHELL both build, exercising both affected
code paths.
