usb: xhci: Set quirk for XHCI_SG_TRB_CACHE_SIZE_QUIRK

stable inclusion
from stable-5.10.2
commit 1bee58e891f26a4246ad10fcc9c8c7e173a898f4
bugzilla: 46859

--------------------------------

commit bac1ec55 upstream.

This commit uses the private data passed by parent device
to set the quirk for Synopsys xHC. This patch fixes the
SNPS xHC hang issue when the data is scattered across
small buffers which does not make atleast MPS size for
given TRB cache size of SNPS xHC.
