usb: host: xhci-plat: Add support for XHCI_SG_TRB_CACHE_SIZE_QUIRK

commit 520b391 upstream.

Upstream commit bac1ec5 ("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.
