drm/i915: Clean up some DISPLAY_VER checks

Use the >= and < operators for the DISPLAY_VER checks everywhere.
This is what most of the code does, but especially recently random
pieces of code have started doing this differently for no good reason.

Conversion done with the following cocci:
@find@
expression i915;
constant ver;
@@
(
DISPLAY_VER(i915) <= ver
|
DISPLAY_VER(i915) > ver
)

@script:python inc@
old_ver << find.ver;
new_ver;
@@
coccinelle.new_ver = str(int(old_ver) + 1)

@@
expression find.i915;
constant find.ver;
identifier inc.new_ver;
@@
(
- DISPLAY_VER(i915) <= ver
+ DISPLAY_VER(i915) < new_ver
|
- DISPLAY_VER(i915) > ver
+ DISPLAY_VER(i915) >= new_ver
)
