arm64: dts: rockchip: add overlay for qnap-ts433 device revision
TS433 devices received a board revision adding gpios for per hard-disk
presence-detection and power-control. These board have a PCB-id of at
least 12 (mainboard) and 10 (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. The
JMicron AHCI controller on PCIe didn't have bindings for that, I could
find, so they get an always-on state for now.
