Subject: [PATCH 4.4 34/91] MIPS: ralink: Fix mt7620 nd_sd pinmux

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

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

From: Mathias Kresin <dev@...sin.me>

commit 7d35baa4e9ec4b717bc0e58a39cdb6a1c50f5465 upstream.

In case the nd_sd group is set to the sd-card function, Pins 45 + 46 are
configured as GPIOs. If they are blocked by the sd function, they can't
be used as GPIOs.
