The-going e31992ae7c sun55iw3: move patches to archive/sunxi-dev-6.16 folder
When patches outside the series are in the target folder
KERNELPATCHDIR = "archive/sunxi- $ {KERNEL _ MAJOR _ MINOR}"
they create problems for all other patches in the series
and are difficult to move to the new kernel version because
they are not properly designed.

Move the patches to a separate development folder until
the design is fixed so that we can add them to the series.

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.
Add a reset entry for it at the end of the existing ones.
Fixes: 8cea339cfb81 ("clk: sunxi-ng: add support for the A523/T527 PRCM CCU")
