zynqmp: Add ATF support for Data blob encryption and decryption

This patch adds ATF support for AES data blob encrypt/decrypt.
ATF establishes a path to send the address of the structure
to the xilsecure, so that it will pick addresses of the data
and performs the requested operation (encrypt/decrypt) and puts
the result in load address.

where structure contains
- Data blob src address
- load address
- IV address
- Key address - this will actual key addr in case of KUP
		else it will be zero.
- Data-size
- Aes-op type
- KeySrc
