iommu/omap: Remove iopgtable_clear_entry_all() from driver remove The function iopgtable_clear_entry_all() is used for clearing all the page table entries. These entries are neither created nor initialized during the OMAP IOMMU driver probe, and are managed only when a client device attaches to the IOMMU. So, there is no need to invoke this function on a driver remove. Removing this fixes a NULL pointer dereference crash if the IOMMU device is unbound from the driver with no client device attached to the IOMMU device.
