arm64: dts: rockchip: add overlay for qnap-ts233 device revision

Browse source

TS233 devices received a board revision adding gpios for per hard-disk
presence-detection and power-control. These boards have a PCB-id of at
least 12 (mainboard) and 11 (backplane), which can be read from an EEPROM.

The presence detection is not really necessary and there are also no
existing bindings for doing something with it. So add them as gpio hogs
to at least document them and allow their state to be read from debugfs.

The power-control is modelled as regulators, with the hdd1+hdd2 variants
connected to the RK3568's SATA controllers as target-supplies.
