ARM: 8739/1: NOMMU: Setup VBAR/Hivecs for secondaries cores
With switch to dynamic exception base address setting, VBAR/Hivecs
set only for boot CPU, but secondaries stay unaware of that. That
might lead to weird effects when trying up to bring up secondaries.
Fixes: ad475117d201 ("ARM: 8649/2: nommu: remove Hivecs configuration is asm")
