arch-arm: Move GICv3 detection at startup time

At the moment the haveGicV3 parameter is used only to signal its
presence when reading the MISCREG_ID_AA64PFR0_EL1 register.  It depends
on the system->getGIC pointing to a GICv3 model.  However this pointer
is set in the System only at init time (after construction), which means
that the haveGICv3CPUInterface will always be false.
This patch is fixing this by moving the parameter initialization at
startup time, together with the cpu interface registration.
