soc/amd/picasso: clean up and re-sort UPD table
Clean up the unused UPD and re-sort the table, and also update
the new phy parameter in the soc code and overridetree.
remove:
EDpPhySel
EDpVersion
rename:
DpPhyOverride -> edp_phy_override
EDpPhySel -> edp_physel
DpVsPemphLevel -> edp_dp_vs_pemph_level
MarginDeemPh -> edp_margin_deemph
Deemph6db4 -> edp_deemph_6db_4
BoostAdj -> edp_boost_adj
eDP phy setting:
DP_VS_LEVEL0_PREEMPH_LEVEL0 = 0x00(0.4v 0db swing 0,pre-emphasis 0)
COMMON_MAR_DEEMPH_NOM = 0x004b
COMMON_SELDEEMPH60 = 0x0
CMD_BUS_GLOBAL_FOR_TX_LANE0 = 0x80
BUG=b:171269338
BRANCH=zork
TEST=Build, verify the parameter pass to picasso-fsp
