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.

HW accelerated hash operations are giving incorrect hash output.
so add flush and invalidate for input/output hash buffers.

RNG Hardware error is reported due to incorrect entropy delay

rng self test are run to determine the correct ent_dly.
test is executed with different voltage and temperature to identify the
worst case value for ent_dly. after adding a margin value(1000),
ent_dly should be at least 12000.

HW accelerated hash operations are giving incorrect hash output.
so invalidate cache lines to avoid cache overwriting in DDR memory region.

 -moved address alignment check in the beginning of function.
 -added invalidate_dcache_range for pout buffer before running descriptor.
