[Intel-gfx] [RFC 0/7] start hiding away vbt structure from the driver

[Jani Nikula]

The VBT is a monster and it keeps growing. Originally we've extracted
bits and pieces out of there, and added them cleanly to our own
structures in dev_priv->vbt, with our own macros. Later on we've been
slipping and we have copied stuff from VBT verbatim, using the same
structs and defines as in VBT.

Start abstracting the VBT more, hiding away the VBT specific stuff that
should not be fiddled with outside of intel_bios.c. Make it more
explicit when we're doing so. At this stage, mostly just fork the
private parts into intel_bios_private.h. As prep work, move some stuff
to intel_bios.c to limit the amount of macros needing to be exposed
across the whole driver.

I think this is the right direction, but this has plenty of bikeshedding
potential. Therefore here's an early RFC. This is based on [1] but the
conflicts are small.

BR,
Jani.
