Subject: [PATCH 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,enable_guctl1_resume_quirk" 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 after EOR.
  This option is to support certain legacy ULPI PHYs.
