imx: imx8ulp_evk: Skip init DDR for reboot in dual boot mode

When M33 is LPAV owner in dual boot, DDR, PCC5, CGC2 won't be reset
during APD reset. So no need to init DDR again after reboot, but need to
reconfigure the PLL4 PFD/PFDDIV/LPAV NIC etc, because kernel may
change or disable some of them.
