target/arm: Allow board models to specify initial NS VTOR

Browse source 
Currently we allow board models to specify the initial value of the
Secure VTOR register, using an init-svtor property on the TYPE_ARMV7M
object which is plumbed through to the CPU.  Allow board models to
also specify the initial value of the Non-secure VTOR via a similar
init-nsvtor property.
