[RFC PATCH 2/7] ASoC: Intel: Kconfig: Simplify-clarify ACPI/PCI dependencies

[Pierre-Louis Bossart]

PCI/ACPI selections should not happen in Kconfig for machine drivers,
move to SOC selections.

Add distinction between PCI and ACPI HiFi2 platforms. The PCI-based
platforms may be removed at some point since Medfield is not really
supported by anyone and there is no publicly available firmware for
Merrifield.

There should be no functionality change.
