mmc: atmel-mci: Remove AVR32 bits from the driver
AVR32 is gone. Now it's time to clean up the driver by removing leftovers that was used by AVR32 related code. Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Acked-by: Ludovic Desroches <ludovic.desroches@microchip.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>
