[Intel-gfx] [PATCH v2] drm/i915/dg2: fix snps buf trans for uhbr

[Jani Nikula <jani.nikula@intel.com>]

The UHBR check was using > instead of >=. Use the helper instead to
avoid mistakes. Also always use the non-UHBR values for HDMI.

v2: Use intel_crtc_has_dp_encoder() && intel_dp_is_uhbr() (Ville)

Fixes: 2817efaeb608 ("drm/i915/dg2: add SNPS PHY translations for UHBR link rates")
