[PATCH RESEND 3/7] iommu/arm-smmu: Add dependency on io-pgtable format modules

The SMMU driver depends on the availability of the ARM LPAE
io-pgtable format code to work properly. In preparation
for having the io-pgtable formats as modules, add a "pre"
dependency with MODULE_SOFTDEP() to ensure that the ARM LPAE
io-pgtable format module is loaded before loading the ARM SMMU
driver module. Also, add a dependency on the ARMv7 short descriptor
io-pgtable format, so that it can be loaded before the SMMU driver
module, if available.
