[0/2] mmc: meson-gx: support platform interrupt as card detect interrupt

On certain platforms like Amlogic Meson gpiod_to_irq() isn't supported
due to the design of gpio / interrupt controller. Therefore provide an
option to specify the cd interrupt e.g. by device tree. The host
controller can store the interrupt in cd_irq for use by
mmc_gpiod_request_cd_irq().
