[ Upstream commit a3332b7aad346b14770797e03ddd02ebdb14db41 ]
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.
