ASoC: Intel: sof_es8336: use NHLT information to set dmic and SSP

Since we see a proliferation of devices with various configurations,
we want to automatically set the DMIC and SSP information. This patch
relies on the information extracted from NHLT and partially reverts
existing DMI quirks added by commit a164137ce91a ("ASoC: Intel: add
machine driver for SOF+ES8336")

Note that NHLT can report multiple SSPs, choosing from the
ssp_link_mask in an MSB-first manner was found experimentally to work
fine.

The only thing that cannot be detected is the GPIO type, and users may
want to use the quirk override parameter if the 'wrong' solution is
provided.
