sw_apps:zynqmp_fsbl: Skip power-up requests for QEMU
QEMU doesn't model PMU in signle arch. Since, in FSBL, it couldn't be determined if QEMU is of single or multi arch, for now skipping power-up request for both cases. Signed-off-by: Sarat Chand Savitala <saratcha@xilinx.com> Acked-by: Krishna Chaitanya Patakamuri <kpataka@xilinx.com>
