crypto: atmel - refine Kconfig dependencies
With the new authenc support, we get a harmless Kconfig warning:
warning: (CRYPTO_DEV_ATMEL_AUTHENC) selects CRYPTO_DEV_ATMEL_SHA which has unmet direct dependencies (CRYPTO && CRYPTO_HW && ARCH_AT91)
The problem is that each of the options has slightly different dependencies,
although they all seem to want the same thing: allow building for real AT91
targets that actually have the hardware, and possibly for compile testing.
This makes all four options consistent: instead of depending on a particular
dmaengine implementation, we depend on the ARM platform, CONFIG_COMPILE_TEST
as an alternative when that is turned off. This makes the 'select' statements
work correctly.
Fixes: 89a82ef87e01 ("crypto: atmel-authenc - add support to authenc(hmac(shaX), Y(aes)) modes")
