I'm fine with this for now, but the gpio-syscon driver is now growing
big and when you use it you are getting support for a whole bunch
of systems you're not running on included in your binary.
We need to think about possibly creating drivers/gpio/syscon
and split subdrivers into separate files and config options
so that people can slim down to what they actually need.

Please do this:
*bit = BIT(offset);
