soc/mediatek/mt8188: Enable and initialize EINT

Issue:
Device can't wake up using power key.

Root cause and solution:
EINT event mask register is used to mask EINT wakeup sources. All
wakeup sources are masked by default. So we add a driver here to unmask
all wakeup sources.

BUG=none
TEST=wake the device up by power key on MT8188 EVB.
