[RFC PATCH 1/4] drm/dp: Rename DPCD 248h according to DP 2.0 specs

DPCD 248h name was changed from “PHY_TEST_PATTERN” in DP 1.4 to “LINK_QUAL_PATTERN_SELECT” in DP 2.0.
Also, DPCD 248h [6:0] is the same as DPCDs 10Bh/10Ch/10Dh/10Eh [6:0]. So removed the repeated definition of PHY patterns.
Reference: “DPCD 248h/10Bh/10Ch/10Dh/10Eh Name/Description Consistency”
