crypto/fsl: SEC driver cleanup for 64 bit and endianness

Browse source 
The SEC driver code has been cleaned up to work for 64 bit
physical addresses and systems where endianess of SEC block
is different from the Core.
Changes:
1. Descriptor created on Core is modified as per SEC block
   endianness before the job is submitted.
2. The read/write of physical addresses to Job Rings will
   be depend on endianness of SEC block as 32 bit low and
   high part of the 64 bit address will vary.
3. The 32 bit low and high part of the 64 bit address in
   descriptor will vary depending on endianness of SEC.
