This patch should fix both issues.  Thanks,

Subject: crypto: atmel - Fix authenc compile test warnings

The authenc code depends on the sha code so in order to allow
compile testing on the former we must allow it on sha as well.

This patch enables compile testing on sha as well as tdes and
fixes the few x86-64 warnings that arise in the sha code.
