drm/i915: Eliminate IS_MTL_GRAPHICS_STEP
[ Upstream commit 5a213086a025349361b5cf75c8fd4591d96a7a99 ]
Several workarounds are guarded by IS_MTL_GRAPHICS_STEP. However none
of these workarounds are actually tied to MTL as a platform; they only
relate to the Xe_LPG graphics IP, regardless of what platform it appears
in. At the moment MTL is the only platform that uses Xe_LPG with IP
versions 12.70 and 12.71, but we can't count on this being true in the
future. Switch these to use a new IS_GFX_GT_IP_STEP() macro instead
that is purely based on IP version. IS_GFX_GT_IP_STEP() is also
GT-based rather than device-based, which will help prevent mistakes
where we accidentally try to apply Xe_LPG graphics workarounds to the
Xe_LPM+ media GT and vice-versa.
v2:
- Switch to a more generic and shorter IS_GT_IP_STEP macro that can be
used for both graphics and media IP (and any other kind of GTs that
show up in the future).
v3:
- Switch back to long-form IS_GFX_GT_IP_STEP macro. (Jani)
- Move macro to intel_gt.h. (Andi)
v4:
- Build IS_GFX_GT_IP_STEP on top of IS_GFX_GT_IP_RANGE and
IS_GRAPHICS_STEP building blocks and name the parameters from/until
rather than begin/fixed. (Jani)
- Fix usage examples in comment.
v5:
- Tweak comment on macro. (Gustavo)
