[PATCH] crypto: fix FTBFS with ARM SHA1-asm and THUMB2_KERNEL

[Matt Sealey]

The optimized assembler SHA1 code for ARM does not conform to Thumb2
register usage requirements, so it cannot be built when the kernel is
configured with THUMB2_KERNEL.

Fix the FTBFS for now by preventing misconfigurations of the kernel.
