Subject: [PATCH 4.14 020/148] usb: xhci: apply XHCI_SUSPEND_DELAY to AMD XHCI controller 1022:145c

From: Alberto Mattea <alberto@...tea.info>

commit 16263abc12d09871156a1c8650fb651f0e552f5e upstream.

This controller timeouts during suspend (S3) with
[  240.521724] xhci_hcd 0000:30:00.3: WARN: xHC save state timeout
[  240.521729] xhci_hcd 0000:30:00.3: ERROR mismatched command completion event
thus preventing the system from entering S3.
Moreover it remains in an undefined state where some connected devices stop
working until a reboot.
Apply the XHCI_SUSPEND_DELAY quirk to make it suspend properly.
