iommu/arm-smmu: replace devm_request_and_ioremap by devm_ioremap_resource
Use devm_ioremap_resource instead of devm_request_and_ioremap.
This was partly done using the semantic patch
scripts/coccinelle/api/devm_ioremap_resource.cocci
The error-handling code on the call to platform_get_resource was removed
manually, and the initialization of smmu->size was manually moved lower, to
take advantage of the NULL test on res performed by devm_ioremap_resource.
