Subject: [PATCH] soc/mediatek/mt8196: Add unmask eint event for bootblock

EINT event mask register is used to mask EINT wakeup source. All wakeup
sources are masked by default. Since most MediaTek SoCs do not have this
design, we can't modify the kernel EINT upstream driver to solve the
issue "Can't wake using power button (cros_ec) or touchpad". So we add a
driver here to unmask all wakeup sources.

TEST=write eint data successfully.
BUG=b:317009620
