usb: host: xhci-plat: Add support for XHCI_SG_TRB_CACHE_SIZE_QUIRK
Upstream commit bac1ec551434 ("usb: xhci: Set quirk for XHCI_SG_TRB_CACHE_SIZE_QUIRK") introduced a new quirk in XHCI which fixes XHC timeout, which was seen on synopsys XHCs while using SG buffers. Currently this quirk can only be set using xhci private data. But there are some drivers like dwc3/host.c which adds adds quirks using software node for xhci device. Hence set this xhci quirk by iterating over device properties.
