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.
