[PATCH 5/6] iommu/arm-smmu: remove redundant calculation of gr0 base address

[Will Deacon]

Since commit 1463fe44fd0f ("iommu/arm-smmu: Don't use VMIDs for stage-1
translations"), we don't need the GR0 base address when initialising a
context bank, so remove the useless local variable and its init code.
