drm/i915/xe2lpd: Extend Wa_15010685871 



Xe2_LPD also needs workaround 15010685871. While adding the new display
version, also re-order the condition to follow the convention of new
version first.

v2: Remove redundant HAS_CDCLK_SQUASH(). As the platform or IP version
    needing the workaround are handpicked, there is no need to also
    check if tha platform has squashing support (Matt Roper)
