Mathias Kresin e142173e8d ramips: backport MT7628 pinmux fixes
According to the datasheet the REFCLK pin is shared with GPIO#37 and
the PERST pin is shared with GPIO#36.

While at it fix a typo inside the pinmux setup code. The function is called
refclk and not reclk.

Update device tree source files accordingly.
