mmc: cd-gpio: pass IRQF_ONESHOT to request_threaded_irq()
Fix a boot regression on Mackerel boards with sh_mobile_sdhi
in existing kernels causing:
genirq: Threaded irq requested with handler=NULL and !ONESHOT for irq XXX
caused by 1c6c6952 (genirq: Reject bogus threaded irq requests).
This is backported from Guennadi's patch:
"mmc: extend and rename cd-gpio helpers to handle more slot GPIO functions"
