Subject: [PATCH v3 06/20] ASoC: mediatek: mt6359-accdet: Implement HP_EINT
 polarity configuration

From: Andrew Perepech <andrew.perepech@...iatek.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.
