acpi/tests/avocado/bits: some misc fixes

Most of the changes are trivial. The bits test timeout has now been increased
to 200 seconds in order to accommodate slower systems and fewer unnecessary
failures. Removed of the reference to non-existent README file in docs. Some
minor corrections in the doc file.
