ARM: 5957/1: ARM: RealView SD/MMC Card detection and write-protect using GPIOLIB
The switch to using GPIOLIB broke the sd/mmc card detection on the
RealView development boards if GPIO_PL061 was not selected.
This patch selects GPIO_PL061 if GPIOLIB is selected.
The sense of the return value from mmc_status has also changed
and is corrected.
