avr32: clean up mci platform code
This patch does a few small cleanups around the atmel mci platform code and in the atmel-mci driver. The platform changes simply removes an unused variable, uses the fact that by the end we always have some form of platform data and notes that GPIO_PIN_NONE != 0. This last point could cause the incorrect attempt to twice reserve pin PA0. While we've got the hood up, add linux/err.h to the atmel-mci.c include list. It needs it and generally pulls it by voodoo but I did once stumble across a config which don't build. This is against Linus' latest git.
