[PATCH v3] ASoC: atmel: ATMEL drivers don't need HAS_DMA

[Randy Dunlap]

On a config (such as arch/sh/) which does not set HAS_DMA when MMU
is not set, several ATMEL ASoC drivers select symbols that cause
kconfig warnings. There is one "depends on HAS_DMA" which is no longer
needed. Dropping it eliminates the kconfig warnings and still builds
with no problems reported.

Fix the following kconfig warnings:
