Subject: [PATCH] ARM: dts: at91: sam9x60: fix mux-mask for PA7 so it can be set to A, B and C

From: Federico Pellegrin <fede@...lware.org>

According to the datasheet PA7 can be set to either function A, B or
C (see table 6-2 of DS60001579D). The previous value would permit just
configuring with function C.
