[PATCH] xilinx: zynqmp: Fix SPL_FS_LOAD_PAYLOAD_NAME usage

[Michal Simek]

SPL_FS_LOAD_PAYLOAD_NAME depends on SPL to be enabled.
If SPL is not enabled code still expects SPL_FS_LOAD_PAYLOAD_NAME to be
present. That's why setup proper dependency in the code.
And by doing so also change the logic around dfu_alt_info string
composition to be simpler.
