The patch was copied to a bunch of platforms and seems to be a quite useful feature for various things. Move it to generic to avoid code duplication.
Follow up to the discussion in https://github.com/openwrt/openwrt/pull/1814#issuecomment-462942022.
We should rather try to get rid of the patch instead of encourage people of using it. Has to be read as soft NAK.
The patch was a hack for missing kernel functionality and was rejected upstream a long time ago. The main use case for the patch is pulling reset GPIOs or enable a USB VCC supply. More and more drivers/subsystems are getting support to control reset GPIOs or enable the VCC supply on their own.
The upstream answer to gpio-exports are gpio-hogs. It is just that nobody migrated the devicetree source files to GPIO hogs so far. Even if gpio-hogs are still a workaround for drivers not able pull their reset GPIOs/enable VCC supply, it seem to me the cleaner workaround.
