ARM: GIC: don't disable software generated interrupts

Software generated interrupts (SGI) are used for IPIs by the kernel.
While previous revisions of the GIC hardware were specified not to
implement enable bits for SGIs, more recent hardware is now permitted
to implement these bits in a per-CPU banked register.

The priority registers for the PPI and SGIs are also per-CPU banked
registers, so ensure that these are also appropriately initialized.
