phy: qcom: edp: Add SC7280/SC8180X swing/pre-emphasis tables

SC7280 and SC8180X previously shared the same cfg because they did not use
swing/pre-emphasis tables. Add the corresponding tables for these
platforms. Since they have different PHY sub-versions, their eDP/DP mode
tables also differ, so move SC8180X to its own cfg instead of reusing the
SC7280 one.
