Subject: [PATCH v2 2/2] phy: qcom-qmp-pcie: add x4 lane EP support for
 QCS9100

Add support for x4 lane end point mode PHY found on QCS9100 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.
QCS9100 is drived from SA8775p. Currently, both the QCS9100 and SA8775p
platform use non-SCMI resource. In the future, the SA8775p platform will
move to use SCMI resources and it will have new sa8775p-related device
tree. Consequently, introduce "qcom,qcs9100-qmp-gen4x2-pcie-phy" and
"qcom,qcs9100-qmp-gen4x4-pcie-phy" to the qmp pcie device match table.
