Without armv8_setup_psci register VBAR_EL3 is not set up property which makes SMC calls jump to invalid location.
smp_kick_all_cpus is required to make slave cpus leave gic_wait_for_interrupt. Without this they will never pursue booting process.
Fix was applied to the two ways of booting VxWorks: bootvx and bootm commands.
This implementation is very similiar to what is done in boot_jump_linux in arch/arm/lib/bootm.c file.
Tested on VxWorks 7 release SR0520 2017-12-08.
