[PATCH 2/2] pmdomain: sunxi: Add support for A733 to Allwinner PCK600 driver

[Yuanshen Cao <alex.caoys@gmail.com>]

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.

Make reset optional in the sunxi pck600 driver and add support
for A733.
