ipq9574 is a TME-L based platform in which before
encrypt/decrypt, we are required to derive a key
handle.
This patch adds support for the same.

Encryptio/Decryption
- For encryption/decryption, plain data/
encrypted date has to be written to memory
directly using mw command along with
ivadata, type and mode
- Implemented new uboot command "aes_256"
to receive the memory address where the
above data is written to
- Perfom basic sanity check against the data
received and send them to secure world through
scm calls
- This is supported only for HK/CYP, hence not
implemented for TZ running in 32bit mode
