drm/i915: Read graphics/media/display arch version from hw
Going forward, the hardware teams no longer consider new platforms to
have a "generation" in the way we've defined it for past platforms.
Instead, each IP block (graphics, media, display) will have their own
architecture major.minor versions and stepping ID's which should be read
directly from a register in the MMIO space.
Bspec: 63361, 64111
v2:
- Move the IP version readout to intel_device_info.c
- Convert the macro into a function
v3:
- Move subplatform init to runtime early init
- Cache runtime ver, release info to compare with hardware values.
- Use IP_VER for snaity check(MattR)
v4:
- Minor doccumentation changes.
- Normalize HAS_GMD_ID macro value.(JaniN)
