xhci: Don't perform Soft Retry for Etron xHCI host

Since commit f8f80be501aa ("xhci: Use soft retry to recover faster from
transaction errors"), unplugging USB device while enumeration results in
errors like this:

[ 364.855321] xhci_hcd 0000:0b:00.0: ERROR Transfer event for disabled endpoint slot 5 ep 2
[ 364.864622] xhci_hcd 0000:0b:00.0: @0000002167656d70 67f03000 00000021 0c000000 05038001
[ 374.934793] xhci_hcd 0000:0b:00.0: Abort failed to stop command ring: -110
[ 374.958793] xhci_hcd 0000:0b:00.0: xHCI host controller not responding, assume dead
[ 374.967590] xhci_hcd 0000:0b:00.0: HC died; cleaning up
[ 374.973984] xhci_hcd 0000:0b:00.0: Timeout while waiting for configure endpoint command

Seems that Etorn xHCI host can not perform Soft Retry correctly, apply
XHCI_NO_SOFT_RETRY quirk to disable Soft Retry and then issue is gone.

This patch depends on commit a4a251f8c235 ("usb: xhci: do not perform
Soft Retry for some xHCI hosts").

Fixes: f8f80be501aa ("xhci: Use soft retry to recover faster from transaction errors")
