Subject: [PATCH v2 0/2] Add support for xhci-sg-trb-cache-size-quirk

XHCI_SG_TRB_CACHE_SIZE_QUIRK was introduced in XHCI to resolve
XHC timeout while using SG buffers, which was seen Synopsys XHCs.
The support for this isn't present in DWC3 layer, this series
enables XHCI_SG_TRB_CACHE_SIZE_QUIRK since this is needed for
DWC3 controller.

Changes in v2:
Included xhci-plat.c to pass the quirks via priv data.
Added Fixes tag in device tree binding patch.
