[PATCH v2 0/2] phy: qcom-qmp-usb: fix initialization of PCS_USB

This series attempts at making sure PCS_USB registers are properly
initialized. I tested it on the sa8775p. AFAICT there's no noticeable
change before/after the patch series: lsusb and dmesg output are the same.
USB is still working properly. I don't know what those PCS_USB registers
do exactly on the qmp PHY and I don't have access to the PHY datasheet, so
it's hard for me to tell the impact of them being initialized vs not.

v1 -> v2:
- Don't fallback to pcs for PCS_USB initialization (Dmitry Baryshkov)

  phy: qcom-qmp-usb: split PCS_USB init table for sc8280xp and sa8775p
