drm/i915/display: use x100 version for full version and release

Use x100, or ver * 100 + rel, versions for full IP version checks,
similar to what xe driver does:

- Replace IP_VER(14, 1) inline with 1401, etc.

- Convert DISPLAY_VER_FULL() to DISPLAY_VERx100()

- Convert IS_DISPLAY_VER_FULL() to IS_DISPLAY_VERx100()

- Convert IS_DISPLAY_VER_STEP() to IS_DISPLAY_VERx100_STEP()

This makes ver.rel versions easier to use, follows the xe driver
pattern, and drops the dependency on the IP_VER() macro.

v2: Rebase, drop IP_VER() from xe compat headers

v3: Rebase
