iommu/io-pgtable-arm: Remove arm_lpae_dump_ops()

At the moment, if the selftest fails it prints a lot of information
about the page table (size, levels...) this requires access to many
internals, which has to be exposed in the next patch moving the
tests out.

Instead, we can simplify the print to only print the fmt and
for each test ias, oas and pgsize_bitmap are already printed.
That is enough to identify the failed case, and the rest can
be deduced from the code.
