Some pmics of the mt6397 family (such as MT6358), have two IRQs per
physical key: one for press event, another for release event.
The mtk-pmic-keys driver assumes that each key only has one
IRQ. The key index and the RES_IRQ resource index have a 1/1 mapping.
This won't work for MT6358, as we have multiple resources (2) for one key.
To prepare mtk-pmic-keys to support MT6358, retrieve IRQs by name
instead of by index.
