drm/i915/display: rename display version macros
While converting the rest of the driver to use GRAPHICS_VER() and
MEDIA_VER(), following what was done for display, some discussions went
back on what we did for display:
1) Why is the == comparison special that deserves a separate
macro instead of just getting the version and comparing directly
like is done for >, >=, <=?
2) IS_DISPLAY_RANGE() is weird in that it omits the "_VER" for
brevity. If we remove the current users of IS_DISPLAY_VER(), we
could actually repurpose it for a range check
With (1) there could be an advantage if we used gen_mask since multiple
conditionals be combined by the compiler in a single and instruction and
check the result. However a) INTEL_GEN() doesn't use the mask since it
would make the code bigger everywhere else and b) in the cases it made
sense, it also made sense to convert to the _RANGE() variant.
So here we repurpose IS_DISPLAY_VER() to work with a [ from, to ] range
like was the IS_DISPLAY_RANGE() and convert the current IS_DISPLAY_VER()
users to use == and != operators. Aside from the definition changes,
this was done by the following semantic patch:
@@ expression dev_priv, E1; @@
- !IS_DISPLAY_VER(dev_priv, E1)
+ DISPLAY_VER(dev_priv) != E1
