[PATCH] ASoC: fix unmet dependencies on PPC_BESTCOMM and SND_SOC_AC97_BUS

SND_MPC52xx_SOC_PCM030 and SND_MPC52xx_SOC_EFIKA both select
SND_SOC_MPC5200_AC97 without ensuring that its dependency on PPC_BESTCOMM is
met. This causes unmet dependencies such as:

WARNING: unmet direct dependencies detected for SND_SOC_MPC5200_AC97
  Depends on [n]: SOUND [=m] && SND [=m] && SND_SOC [=m] && SND_POWERPC_SOC [=m] && PPC_BESTCOMM [=n]
  Selected by [m]:
  - SND_MPC52xx_SOC_PCM030 [=m] && SOUND [=m] && SND [=m] && SND_SOC [=m] && SND_POWERPC_SOC [=m] && PPC_MPC5200_SIMPLE [=y]

SND_MPC52xx_SOC_EFIKA also selects SND_SOC_STAC9766 without ensuring its
dependency on SND_SOC_AC97_BUS is met.

Let's resolve all 3 unmet dependencies by adding the dependencies on
PPC_BESTCOMM where needed, and selecting SND_SOC_AC97_BUS as other, similar
options in this subsystem do.

These unmet dependency bugs were detected by kconfirm, a static analysis tool
for Kconfig.

Fixes: a9262c4fd404 ("ASoC: Support for AC97 on Phytec pmc030 base board.")
Fixes: 6ffee43ecf8b ("ASoC: Fabric bindings for STAC9766 on the Efika")
