Most of the IS_METEORLAKE checks in the display code shouldn't actually
be tied to MTL as a platform, but rather to the Xe_LPD+ display IP
(which is used in MTL, but may show up again in future platforms). In
cases where we're trying to match that specific IP, use a version check
against IP_VER(14, 0). For cases where we're just handling new behavior
introduced by this IP (but which may also be inherited by future IP as
well), use a ver >= 14 check.
The one exception here is the stolen memory workaround Wa_13010847436
(which is mislabelled as "Wa_22018444074" in the code). That's truly a
MTL-specific issue rather than being tied to any of the IP blocks, so
leaving the condition as IS_METEORLAKE is correct there.
v2:
- cdclk check should be >=, not >. (Gustavo)
