power: pmic: mtk-pwrap: remove interrupt related code

Remove the interrupt related code in mtk-pwrap driver. This was just
enabling interrupts without any handler.

Even if we did have a handler, the only thing we could do is log a
message. Since U-Boot isn't long running, this likely wouldn't be very
useful.
