Subject: [PATCH][RESEND] ASoC: Intel: atom: fix ACPI/PCI Kconfig

The split between ACPI and PCI platforms generated issues with randconfig:

with SND_SST_ATOM_HIFI2_PLATFORM_PCI=y and
SND_SST_ATOM_HIFI2_PLATFORM=m, we get this module link failure:

ERROR: "sst_context_init"
[sound/soc/intel/atom/sst/snd-intel-sst-acpi.ko] undefined!

ERROR: "sst_context_cleanup"
[sound/soc/intel/atom/sst/snd-intel-sst-acpi.ko] undefined!

ERROR: "sst_alloc_drv_context"
[sound/soc/intel/atom/sst/snd-intel-sst-acpi.ko] undefined!

ERROR: "intel_sst_pm" [sound/soc/intel/atom/sst/snd-intel-sst-acpi.ko]
undefined!

ERROR: "sst_configure_runtime_pm"
[sound/soc/intel/atom/sst/snd-intel-sst-acpi.ko] undefined!

To keep things simple, let's expose two configs for
SND_SST_ATOM_HIFI2_PLATFORM_PCI and SND_SST_ATOM_HIFI2_PLATFORM_ACPI,
which select a common SND_SST_ATOM_HIFI2_PLATFORM option. To avoid
breaking existing solutions with the semantics change,
SND_SST_ATOM_HIFI2_PLATFORM_ACPI uses "default ACPI" so that "make
oldnoconfig" and "make olddefconfig" still work as expected.

Also remove mentions of Medfield while we are at it since it was
removed recently.
