ANDROID: GKI: select DMADEVICES if GKI_HIDDEN_SND_SOC_CONFIGS is set

DMA_VIRTUAL_CHANNELS depends on DMADEVICES and DMA_VIRTUAL_CHANNELS
is selected by GKI_HIDDEN_SND_SOC_CONFIGS.

To fix unmet dependency in x86_64, select DMADEVICES under
GKI_HIDDEN_SND_SOC_CONFIGS.

Also, drop CONFIG_DMADEVICES=y in arch/arm64/configs/gki_defconfig.

WARNING: unmet direct dependencies detected for DMA_VIRTUAL_CHANNELS
  Depends on [n]: DMADEVICES [=n]
    Selected by [y]:
      - GKI_HIDDEN_SND_SOC_CONFIGS [=y]
