[OpenWrt-Devel] [PATCH 3/4] lantiq: Add AR9 compatibility bits to DWC2 driver

[Antti Seppälä]

Add AR9 DTS definition to be recognized by the DWC2 driver.

The same driver parameters can be mostly used except that some boards 
seem to erroneously report OTG HNP/SRP capability of the USB HCD.
Forcing the HNP/SRP off allows these boards to work with the DWC2 as well.
