pmdomain: sunxi: Add support for A733 to Allwinner PCK600 driver
The Allwinner A733 PCK600, similar to A523 PCK600, is likely a
customized version of ARM PCK-600 power controller. It shares the same
BSP driver with A523. According to the BSP provided by Radxa, unlike
A523, it doesn't require reset, as well as a different pair of delay
values.
Make reset optional in the sunxi pck600 driver and add support
for A733.
