booke/powerpc: define wimge shift mask to fix compilation error

This fixes below compilation error on SOCs where CONFIG_PHYS_64BIT
is not defined:

 arch/powerpc/kvm/e500_mmu_host.c: In function 'kvmppc_e500_shadow_map':
| arch/powerpc/kvm/e500_mmu_host.c:631:20: error: 'PTE_WIMGE_SHIFT' undeclared (first use in this function)
|    wimg = (*ptep >> PTE_WIMGE_SHIFT) & MAS2_WIMGE_MASK;
|                     ^
| arch/powerpc/kvm/e500_mmu_host.c:631:20: note: each undeclared identifier is reported only once for each function it appears in
| make[1]: *** [arch/powerpc/kvm/e500_mmu_host.o] Error 1

This should go to the normal Linux PPC list, no?

I was not sure when sending this fix as this fixes issue for KVM build but code changes are in generic files :)
No I will send on  linuxppc-dev@lists.ozlabs.org
