[085/141] USB: mos7720: fix hardware flow control

[Steven Rostedt]

3.6.11.6 stable review patch.
If anyone has any objections, please let me know.

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

From: Johan Hovold <jhovold@xxxxxxxxx>

[ Upstream commit a26f009a070e840fadacb91013b2391ba7ab6cc2 ]

The register access to enable hardware flow control depends on the
device port number and not the port minor number.
