mfd: arizona-spi: Set pdata.hpdet_channel for ACPI enumerated devs
[ Upstream commit 831d1af85133e1763d41e20414912d9a1058ea72 ]
Commit 9e86b2ad4c11 changed the channel used for HPDET detection
(headphones vs lineout detection) from being hardcoded to
ARIZONA_ACCDET_MODE_HPL (HP left channel) to it being configurable
through arizona_pdata.hpdet_channel the DT/OF parsing added for
filling arizona_pdata on devicetree platforms ensures that
arizona_pdata.hpdet_channel gets set to ARIZONA_ACCDET_MODE_HPL
when not specified in the devicetree-node.
But on ACPI platforms where arizona_pdata is filled by
arizona_spi_acpi_probe() arizona_pdata.hpdet_channel was not
getting set, causing it to default to 0 aka ARIZONA_ACCDET_MODE_MIC.
This causes headphones to get misdetected as line-out on some models.
Fix this by setting hpdet_channel = ARIZONA_ACCDET_MODE_HPL.
