Subject: [PATCH 2/2] phy: qcom-qmp-combo: initialize PCS_USB registers

Currently, PCS_USB registers that have their initialization data in a
pcs_usb_tbl table are never initialized. Fix that.

Fixes: fc64623637da ("phy: qcom-qmp-combo,usb: add support for separate PCS_USB region")
Reported-by: Adrien Thierry <athierry@...hat.com>
