arch-arm: Forward declare kvm_reg_list

The adoption of the gem5 namespace [1] broke aarch64 builds with
the following error:

build/ARM/arch/arm/kvm/base_cpu.cc:198:22: error: aggregate
'gem5::kvm_reg_list regs_probe' has incomplete type and cannot be
defined

In file included from build/ARM/arch/arm/kvm/base_cpu.cc:38:0:
build/ARM/arch/arm/kvm/base_cpu.hh:115:28: note: forward declaration of
'struct gem5::kvm_reg_list'
     std::unique_ptr<struct kvm_reg_list> tryGetRegList(uint64_t nelem)
const;

Forward declaring the struct defined in linux/kvm.hh (included in source
file) in the global namespace, rather than the gem5 one fixes the
problem
