crypto: fsl_hash: Remove unnecessary alignment check in caam_hash()
While working on an LX2160 based board and updating to latest mainline
I noticed problems using the HW accelerated hash functions on this
platform, when trying to boot a FIT Kernel image. Here the resulting
error message:
Using 'conf-freescale_lx2160a.dtb' configuration
Trying 'kernel-1' kernel subimage
Verifying Hash Integrity ... sha256Error: Address arguments are not aligned
CAAM was not setup properly or it is faulty
error!
Bad hash value for 'hash-1' hash node in 'kernel-1' image node
Bad Data Hash
ERROR: can't get kernel image!
Testing and checking with Gaurav Jain from NXP has revealed, that this
alignment check is not necessary here at all. So let's remove this
check completely.
