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.

Regards,
Angelo
