[PATCH] crypto: atmel: remove bogus select

[Arnd Bergmann]

The Atmel at91 crypto driver unconditionally selects AT_HDMAC,
which results in a Kconfig warning if that driver is not enabled:

warning: (CRYPTO_DEV_ATMEL_AES) selects AT_HDMAC which has unmet direct dependencies (DMADEVICES && ARCH_AT91)

The crypty driver itself does not actually have a dependency
on a particular dma engine, other than this being the one that
is used in at91.

Removing the 'select' gets rid of the warning, with no apparent
downsides.
We should probably enable AT_HDMAC in sama5_defconfig, because
it no longers gets enabled implicitly.
