Changes in v6:
- abandon cap-sdio-async-irq flag, use wakeup-source flag instead
- extend interrupts and pinctrls in mediatek mmc host controller DT documents
- add mmc_card_enable_async_irq() to access enable_async_irq flag

Changes in v5:
- resort variables to reversed xmas tree order
- restore old copyright year range and add current year back

Changes in v4:
- add MMC_CAP2_SDIO_ASYNC_IRQ judge before lookup eint pinctrl
- replace spin_lock_irqsave() variant with spin_lock() in eint irq handler

Changes in v2:
- change flag name from 'cap-sdio-async-int' to 'cap-sdio-async-irq'
- change corresponding macro names from xxx_INT to xxx_IRQ
- resort new member in msdc_host structure
- refine function msdc_request_dat1_eint_irq()
- rename msdc_{suspend,resume} function names, add suffix '_noirq'
- add MMC_CAP2_NO_SDIO judgement before parse eint related pin setting
