[Intel-gfx] [PATCH v2 1/2] drm/i915/dp: Use LINK_QUAL_PATTERN_* Phy test pattern names

Starting from DP2.0 specs, DPCD 248h is renamed
LINK_QUAL_PATTERN_SELECT and it has the same values of registers
DPCD 10Bh-10Eh.
Use the PHY pattern names defined for DPCD 10Bh-10Eh in order to add
CP2520 Pattern 3 (TPS4) phy pattern support in the next
patch of this series and DP2.1 PHY patterns for future series.

v2: rebase
