[PATCH v4 14/14] dm: gpio: Add a migration message for GPIO

[Simon Glass]

This probably should have been done a while back since it is a core
system. Add a migration deadline of later this year, to catch the
stragglers.

- Refactored the warning code to make it easier to get this right
- Add GPIO deprecation as well
- Add patches to rename DM_RESET to RESET

- s/'network'/I2C/ again

Changes in v2:
- s/'network'/I2C/
