hw/arm/armsse: Allow boards to specify init-svtor

Browse source 
The Musca boards have DAPLink firmware that sets the initial
secure VTOR value (the location of the vector table) differently
depending on the boot mode (from flash, from RAM, etc). Export
the init-svtor as a QOM property of the ARMSSE object so that
the board can change it.
