zynqmp: restore the jtag interface
When boot.bin is configured for secure boot the CSU will disable the
JTAG interface on all cases.
Some boards might rely on this interface for flashing to QSPI in which
case those systems might end up bricked during development.
This commit will restore the interface under CSU control
