ARM: KVM: Correctly order SGI register entries in the cp15 array
The ICC_ASGI1R and ICC_SGI0R register entries in the cp15 array
are not correctly ordered, leading to a BUG() at boot time.
Move them to their natural location.
Fixes: 3e8a8a50c7ef ("KVM: arm: vgic-v3: Add support for ICC_SGI0R and ICC_ASGI1R accesses")
