usb: phy-msm-qusb-v2: Add chip version check for errata

There was a hardware fix for Chirp Voltage Dp and Dm violation
leading to SSD enumeration failure. The fix is on 1.1 version
of the SoC.

This is a method to distinguish between the two different versions
of the SoC by reading the minor revision number as:
00 : rev 1.0
01 : rev 1.1

Using this method this errata can be worked around for the specific
chip version.
