gpio: bd70528: Use correct unit for debounce times

commit f88c117b6d6d7e96557b6ee143b26b550fc51076 upstream.

The debounce time passed to gpiod_set_debounce() is specified in
microseconds, so make sure to use the correct unit when computing the
register values, which denote delays in milliseconds.
