[Intel-gfx] [PATCH v2 04/12] drm/i915: add macros for graphics and media versions

[Lucas De Marchi]

Like it was done in
commit 01eb15c9165e ("drm/i915: Add DISPLAY_VER() and related macros")
add the correspondent macros for graphics and media. Going forward we
will prefer checking the versions for the specific IPs (graphics, media
and display) rather than grouping everything under a "gen" version.

For consistency and to make the maintenance easier, it'd be preferred
not to mix the *GEN* macros with the new ones. For older platforms we
can simply consider that the previous "gen" number will extend to all
3 IPs. Then we can start replacing its use in the driver. Right now this
replacement is not done and only the infrastructure is put in place.
We also leave gen and gen_mask inside struct intel_device_info while
it's still being used throughout the code.

v2: Repurpose IS_{GRAPHICS,MEDIA}_VER() macros to work with a range
