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. Signed-off-by: Mathias Kresin <dev@kresin.me>
