fpga: zynqmp: support loading encrypted bitfiles
Add supporting new compatible string "u-boot,zynqmp-fpga-enc" to
handle loading encrypted bitfiles.
This feature requires encrypted FSBL, as according to UG1085:
"The CSU automatically locks out the AES key, stored in either BBRAM
or eFUSEs, as a key source to the AES engine if the FSBL is not
encrypted. This prevents using the BBRAM or eFUSE as the key source
to the AES engine during run-time applications."
