The Bananapi-M3 has a SATA connector, driven by a USB-to-SATA bridge soldered on the board. The power for the SATA device is provided by a GPIO controlled regulator. Since the SATA device is behind USB, it has no DT node, so we never described this regulator. Instead U-Boot was turning this on in a rather hackish way, which we now want to get rid of. On top of that it seems fragile to leave this GPIO undescribed, as userland could claim it and turn the disk off. Add a fixed regulator, controlled by the PD25 GPIO, and mark it as always-on. This would mimic the current situation, but in a safer way, and would allow U-Boot to drop the CONFIG_SATAPWR enable hack.
