[kvm-unit-tests PATCH 1/6] arm: gic: check_acked: add test description

[Andre Przywara <andre.przywara@xxxxxxx>]

At the moment the check_acked() IRQ helper function just prints a
generic "Completed" or "Timed out" message, without given a more
detailed test description.

To be able to tell the different IRQ tests apart, and also to allow
re-using it more easily, add a "description" parameter string,
which is prefixing the output line. This gives more information on what
exactly was tested.

This also splits the variable output part of the line (duration of IRQ
delivery) into a separate INFO: line, to not confuse testing frameworks.
