msm: iommu: Don't read from write-only registers
Don't read from V2Pxx command registers when doing iova-to-phys operations. These registers are write-only and reading the value before modifying the VA bits is unnecessary. Signed-off-by: Stepan Moskovchenko <stepanm@codeaurora.org> Signed-off-by: David Brown <davidb@codeaurora.org>
