Subject: [PATCH/RFC] crypto: Add platform dependencies for CRYPTO_DEV_CCREE

The ARM TrustZone CryptoCell is found on ARM SoCs only.  Hence make it
depend on ARM or ARM64, unless compile-testing.

Drop the dependency on HAS_DMA, as DMA is always available on ARM and
ARM64 platforms, and doing so will increase compile coverage.

Is ARM || ARM64 OK?
Or should this be limited to either ARM or ARM64? Or something else?
