From: Arnd Bergmann <arnd@arndb.de>

The linux/gpio.h header used to be the global definition for the gpio
interfaces, with 1100 users back in linux-3.17. In linux-7.2, only about
130 of those remain, so this series cleans out the rest.

In each subsystem, we can replace the header either with
linux/gpio/consumer.h for users of the modern gpio descriptor interface,
or linux/gpio/legacy.h for the few remaining users of the old number
based interface.

All patches in this series can get applied independently, so my
preference would be for each subsystem maintainer to apply these
directly, with the rest going into the gpio tree at some point.

The final patch here obviously needs to wait for all the others
to get merged first.
