Ville Syrjälä aad9699688 drm/i915/cdclk: Avoid spurious cdclk sanitization on PTL+
Apparently PTL+ no longer has the cd2x pipe select field in
CDCLK_CTL. Take that into account during CDCLK sanitization.

This currently triggers a spurious CDCLK sanitization during
driver load on PTL+ which will causes a visible glitch on all
active displays.
