omap: iommu-load cam register before flushing the entry

The flush_iotlb_page is not loading the cam register before flushing
the cam entry. This causes wrong entry to be flushed out from the TLB, and
if the entry happens to be a locked TLB entry it would lead to MMU faults.

The fix is to load the cam register with the address to be flushed before
flushing the TLB entry.
