For unloading an ACPI table, it is necessary to provide the
index of the table. The method intended for dynamically
loading or hotplug addition of tables, acpi_load_table(),
does not provide this information, so a new function
acpi_load_table_with_index() with the same functionality,
but an optional pointer to the loaded table index is introduced.

The new function is used in the acpi_configfs driver to save the
index of the newly loaded table in order to unload it later.

I'll test it later, though couple of remarks:
- would it make sense to provide a counter part helper for unloading? Now it
looks a bit inconsistent in configfs when we use acpi_load_*() vs.
acpi_tb_*() in remove.

Yes, IMO it would make sense, but it is an ACPICA API change. Bob, what's your opinion?


...and I think we may unexport acpi_tb_* in this case as Bob suggested for it
to be internal API.

see above.
