soc: nrf54h: don't boot radio core if VTOR is not programmed

Browse Source 
Booting the radio core when it is not programmed will typically
cause a reset loop. This can happen when programming multiple
images to a device, and the app core image is programmed before
the radio core.

With this change we avoid the reset loop in that case.
