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

From: Geert Uytterhoeven
Date: Tue Apr 17 2018 - 14:14:44 EST


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?
