armv8: Add workaround for USB erratum A-009798
The default setting for USB High Speed Squelch Threshold results
in a threshold close to or lower than 100mV. This leads to Receiver
Compliance test failure for a 100mV threshold.
Shift the threshold from ~100mV towards ~130mV by setting SQRXTUNE
to 0x0 to pass USB High Speed Receiver Sensitivity Compliance test.
