crypto: atmel - fix data types for __be{32,64} 

The driver uses a couple of buffers that seem to
be __be32 or __be64 fields, but declares them as
u32. This means there are a number of warnings
from sparse due to casting to/from __beXXX.

Fix these by changing the types of the buffer
and the associated variables.
