[PATCH v4 06/19] ASoC: mediatek: mt6359-accdet: Drop dead code for EINT/GPIO IRQ handling

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

The ACCDET supports two modes for IRQ generation: PMIC EINT or AP GPIO,
which in principle could be configured through a DT property. However
this DT property has no user nor is documented in a binding, and the
driver only implements the PMIC EINT case, so drop the unused code
intended to handle both cases.
