bsps/arm: Set VBAR in start.S

Browse Source 
Set the VBAR to the vector table in the start section before
bsp_start_hook_0() is called to earlier handle exceptions in RTEMS.

Set the VBAR to the normal vector table in start.S for the main
processor.  Secondary processors set it in bsp_start_hook_0().

Update #4202.
