Subject: [PATCH v9 0/3] mmc: mediatek: add support for SDIO async IRQ

Changes in v9:
- remove pinctrl "state_dat1"

Changes in v8:
- remove maxItems property under pinctrl-names property

Changes in v7:
- add device_init_wakeup() to register SDIO host as wakeup source

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
- simplify wakeup irq implementation with dedicate wake up irq related interface

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 v3:
- correct abbreviations with capital letters in commit message
- replace copyright year with 2022 in mtk-sd.c
- remove unnessary pointer casting
- adjust variable order to reversed xmas tree
- remove a redundant blank line
- refine if statement, following standard pattern

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
