Commit dc6d95b153 ("KVM: MIPS: Add more MMIO load/store
instructions emulation") introduced some 64bit load/store instructions
emulation which are unavailable on 32bit platform, and it causes build
errors:
arch/mips/kvm/emulate.c: In function 'kvm_mips_emulate_store':
arch/mips/kvm/emulate.c:1734:6: error: right shift count >= width of type [-Werror]

cc1: all warnings being treated as errors
make[3]: *** [arch/mips/kvm/emulate.o] Error 1
So, use #if defined(CONFIG_64BIT) && defined(CONFIG_KVM_MIPS_VZ) to
guard the 64bit load/store instructions emulation.
