drm/i915/vga: Introduce intel_vga_{read,write}()

Browse source

VGA register are rather special since they either get accessed
via the global IO addresses, or possibly through MMIO on
pre-g4x platforms. Wrap all VGA register accesses in
intel_vga_{read,write}() to make it obvious where they get
accessed.
