When I boot a kukui-kodama board, I see an ugly warning in my kernel
log:
  mtk-msdc 11240000.mmc: error -ENXIO: IRQ sdio_wakeup not found

It's pretty normal not to have an "sdio_wakeup" IRQ defined. In fact,
no device trees in mainline seem to have it. Let's use the
platform_get_irq_byname_optional() to avoid the error message.

Fixes: 527f36f5efa4 ("mmc: mediatek: add support for SDIO eint wakup IRQ")
