Subject: [PATCH] mmc: core: sdio: Fix unconditional wake_up_process() on sdio
 thread

781e989cf59 ("mmc: sdhci: convert to new SDIO IRQ handling") and
bf3b5ec66bd ("mmc: sdio_irq: rework sdio irq handling") disabled
the use of our own custom threaded IRQ handler, but left in an
unconditional wake_up_process() on that handler at resume-time.

In addition, the check for MMC_CAP_SDIO_IRQ capability is added
before enable sdio IRQ.
