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

From: Daniel Golle <daniel@xxxxxxxxxxxxxx>

[ Upstream commit dfa988b4c7c3a48bde7c2713308920c7741fff29 ]

Setup PMCR port register for actual speed and duplex on internally
connected PHYs of the MT7988 built-in switch. This fixes links with
speeds other than 1000M.
