Guennadi Liakhovetski c9b0546a59 mmc: simplify mmc_cd_gpio_request() by removing two parameters 
Calculate the IRQ number, using gpio_to_irq() and use fixed flags: trigger
on both edges. This makes two out of four arguments of the
mmc_cd_gpio_request() function redundant.

Guennadi Liakhovetski 349ab52446 mmc: add a generic GPIO card-detect helper 
This patch adds a primitive helper to support card hotplug detection on
platforms, where a GPIO, capable of producing interrupts, is used for
detection of card-insertion and -removal events.
