phy: qcom-qmp-pcie: add x4 lane EP support for sa8775p
Add support for x4 lane end point mode PHY found on sa8755p platform.
Reusing existing serdes and pcs_misc table for EP and moved
BIAS_EN_CLKBUFLR_EN register from RC serdes table to common serdes
table as this register is part of both RC and EP.
