Subject: [PATCH] xhci: dbc: Change to pass dbc pointer to xhci_do_dbc_stop()
Git-commit: 903089b7b9d85096f06bee3ee5715fe85b4e8651
References: jsc#SLE-14911
Patch-mainline: v5.9-rc1

Pass the dbc pointer instead of xhci_hcd pointer in order to
decouple xhci and dbc.

xhci_do_dbc_stop() only used xhci to get the dbc pointer.
Pass the dbc pointer instead as a parameter

No functional changes
This change helps decoupling xhci and DbC
