FROMGIT: KVM: arm64: Constify kvm_io_gic_ops

Browse Source 
The only usage of kvm_io_gic_ops is to make a comparison with its
address and to pass its address to kvm_iodevice_init() which takes a
pointer to const kvm_io_device_ops as input. Make it const to allow the
compiler to put it in read-only memory.
