iommu/omap: Remove ver debugfs entry
The debugfs entry 'ver' to read the OMAP IOMMU version is not much useful for developers, so it has been removed. The same can be deduced from the register dump, provided by the debugfs entry 'regs', REVISION register. This also allows us to remove the omap_iommu_arch_revision() which is currently returning a fixed value.
