usb: qmp: phy: Fix register offsets for QMP PHY Rev2

Commit 7322af4c ("usb: phy: Add snapshot of changes from msm-3.10")
brought in multiple fixes on QMP PHY, removed previously used
AUTONOMOUS_MODE_CTRL register offset on 8996 with introducing new register
LFPS_RXTERM_IRQ_CLEAR. These registers' offset are different with QMP PHY
rev2.0. Hence correct used offset value with these registers.
