xhci: Fresco FL1100 controller should not have BROKEN_MSI quirk set.

stable inclusion
from stable-v5.10.90
commit 1933fe8ce712989df8e94966e21d1752fe19c257
bugzilla: 186168 https://gitee.com/openeuler/kernel/issues/I4SHY1

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=1933fe8ce712989df8e94966e21d1752fe19c257

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

commit e4844092 upstream.

The Fresco Logic FL1100 controller needs the TRUST_TX_LENGTH quirk like
other Fresco controllers, but should not have the BROKEN_MSI quirks set.

BROKEN_MSI quirk causes issues in detecting usb drives connected to docks
with this FL1100 controller.
The BROKEN_MSI flag was apparently accidentally set together with the
TRUST_TX_LENGTH quirk

Original patch went to stable so this should go there as well.
