Subject: [PATCH V2 0/2] usb: dwc3: core: Enable GUCTL1 bit 10 for fixing crc error after resume 

This patch of the series does the following:
- Add a new DT "snps,resume-hs-terminations" quirk
- Enable GUCTL1 bit 10 for fixing crc error after resume bug
- When this bit is set to '1', the ULPI opmode will be changed to 'normal'
  along with HS terminations, and term/xcvr select signals after EOR.
  This option is to support certain legacy ULPI PHYs.
---
Changes in V2:
- Addressed Krzysztof Kozlowski review comments
 - Update the quirk name and No underscores in properties.
 - Modified the quirk description.
