KVM: PPC: Replace SPAPR_TCE_SHIFT with IOMMU_PAGE_SHIFT_4K
SPAPR_TCE_SHIFT is used in few places only and since IOMMU_PAGE_SHIFT_4K can be easily used instead, remove SPAPR_TCE_SHIFT. Signed-off-by: Alexey Kardashevskiy <aik@ozlabs.ru> Reviewed-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
