iommu/omap: Remove redundant clock handling on ISR
For the interrupt to be generated, the mmu clock should be already enabled while translating a virtual address, so, this call to clock handling is just increasing/decreasing the counter. This works now, because its users need the same clock and they indirectly power the mmu, in this interrupt context the handling of clocks inside the ISR doesn't seem to be needed nor helping. Next patch should also correct the dependency on clients to handle iommu clocks.
