Subject: [PATCH 04/15] arm/omap: use generic_file_llseek in iommu_debug

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.
