[PATCH v4 05/19] ASoC: mediatek: mt6359-accdet: Implement HP_EINT polarity configuration

["Nícolas F. R. A. Prado" <nfraprado@collabora.com>]

From: Andrew Perepech <andrew.perepech@mediatek.com>

The driver currently reads the HP_EINT polarity from the Devicetree but
never actually configures the hardware accordingly.

Implement the polarity configuration in hardware.
