From: Chen-Yu Tsai <redacted> There is a PPU0 reset control bit in the same register as the PPU1 reset control. This missing reset control is for the PCK-600 unit in the SoC. Manual tests show that the reset control indeed exists, and if not configured, the system will hang when the PCK-600 registers are accessed.
Confirmed by experiment.
Add a reset entry for it at the end of the existing ones.
