Extend interrupts and pinctrls for SDIO wakeup interrupt feature.
This feature allow SDIO devices alarm asynchronous interrupt to host
even when host stop providing clock to SDIO card. An extra wakeup
interrupt and pinctrl states for SDIO DAT1 pin state switching are
required in this scenario.

That ain't right. You have two interrupts, so you describe two interrupts:
interrupt-names:
minItems: 1
items:
- const: msdc
- const: sdio-wakeup
...also, I personally don't like the "_irq" suffix: we're specifying interrupts in
interrupt-names, so it sounds a bit redundant.
You're free to keep it, if you really like it though.
