arm64: dts: rockchip: switch Rock 5C to PMIC-based TSHUT reset
Radxa Rock 5C supports both CRU-based (default) and PMIC-based reset
upon thermal runaway conditions. The former resets the SoC by internally
poking the CRU from TSADC, while the latter power-cycles the whole board
by pulling the PMIC reset line low in case of uncontrolled overheating.
Switch to a PMIC-based reset, as the more 'thorough' of the two.
Tested by temporarily setting rockchip,hw-tshut-temp to 65C to simulate
overheating - this causes the board to reset when any of the on-chip
temperature sensors surpasses the tshut temperature.
Requires Alexander's patch [1] fixing TSADC pinctrl assignment
