Mh, does it make sense to pick this one without commit a6fc2f1b0927 ("usb: 
dwc3: core: add gfladj_refclk_lpm_sel quirk")?
snps,gfladj-refclk-lpm-sel-quirk is unknown/unused after this patch, but 
snps,dis-u2-freeclk-exists-quirk is not applied any more.
If a6fc2f1b0927 is not applicable, I would drop this one instead.

Best regards,
Alexander
