pinctrl: mediatek: add input-enable and direction setting for eint resources
To use pin as eint, user should make sure that:
1. pin is set to right mode, this is done in .irq_request_resources
implementation already.
2. direction of the pin is input, which should call GPIO API to set
pin to input gpio.
We add what step 2 do to .irq_request_resources so that user doesn't
need call GPIO API any more when pin for eint usage.
