arm/omap: use generic_file_llseek in iommu_debug

Browse Source 
In future kernels, debugfs files need to specify
the llseek operation explicitly to allow seeking.
This sets the llseek operation in the omap iommu
debugfs files to generic_file_llseek, which is
appropriate for files using simple_read_from_buffer.
