xilinx: zynqmp: Enable SPL for zynqmp mini

The only purpose to enable SPL is to simplify testing of mini
configuration. SPL initializes the system also with DDR that mini
configuration can directly run.
psu_init already targets zcu102 like for mini_qspi
(symlink zynqmp-mini -> zynqmp-zcu102-rev1.0).
