Added the new 'snps,inv-sync-hdr-quirk' DT property to dwc3 core for Gen2 polarity detection. The link uses data block (0011b) sync header for SYNC OS instead of control block (1100b). Set this quirk if the third-party PHY does not correct the sync header of the SYNC OS in the case of inverse polarity.
