drm/i915/display: add display platforms structure with platform members

Browse source

Add a structure with a bitfield member for each platform and
subplatform, and initialize them in platform and subplatform descs.

The structure also contains a bitmap in a union for easier manipulation
of the bits. This, in turn, requires a bit of trickery with
INTEL_DISPLAY_PLATFORMS() to count the number of bits required for
DECLARE_BITMAP().
