The bq24022 regulator is simply a more specialised variant of the now
present gpio-regulator. Therefore it probably shouldn't stay around.
This series converts the two users of bq24022 pxa/hx4700 and
pxa/magician to use the gpio-regulator instead, and after this removes
the then unused bq24022 driver.
The series was compile-tested only, but the gpio-regulator itself is
sucessfully used on my platform for the dcdc3 of a tps650240 (voltage
regulator with one gpio) and for a bq24075 (current regulator with two
gpios). So I'm quite sure it should work correctly but would welcome
testers :-) .

One provides the on/off functionality and a second one is used to change the current between 100 and 500 mA. This functionality can also be provided by the more generic gpio-regulator. Therefore convert both machines which makes it possible to remove the bq24022 driver later on.
