hw/arm/armsse: Unify init-svtor and cpuwait handling

Browse source 
At the moment the handling of init-svtor and cpuwait initial
values is split between armsse.c and iotkit-sysctl.c:
the code in armsse.c sets the initial state of the CPU
object by setting the init-svtor and start-powered-off
properties, but the iotkit-sysctl.c code has its own
code setting the reset values of its registers (which are
then used when updating the CPU when the guest makes
runtime changes).

Clean this up by making the armsse.c code set properties on the
iotkit-sysctl object to define the initial values of the
registers, so they always match the initial CPU state,
and update the comments in armsse.c accordingly.
