phy: qcom-qmp: Fix register name in RX Lane config of SC8280XP

In RX Lane configuration sequence of SC8280XP, the register
V5_RX_UCDR_FO_GAIN is incorrectly spelled as RX_UCDR_SO_GAIN and
hence the programming sequence is wrong. Fix the register sequence
accordingly to avoid any compliance failures. This has been tested
on SA8775P by checking device mode enumeration in SuperSpeed.
