Add libgpiod v2 compatible bitbang master

The API was completely re-invented with libgpiod 2.0. Hence we add a
new driver as we would otherwise only share boilerplate with the old
driver. The new API makes it easier to re-configure GPIO pins on-the-
fly. Which we will use to implement dual- and quad-i/o modes in the
future.

One downside of the new API is that there is no function to open a
chip by number anymore. So we have to emulate that behavior now for
backwards compatibility.
