The A83T's PRCM has the same set of clocks and resets as the A64.
However, a few dividers are different. And due to the lack of a low
speed 32.768 kHz oscillator, a few of the clock parents are different.

The PRCM also has controls for various power domains. These are not
supported yet, neither in software nor in the device tree binding.

Add node for SPI NOR flash on orange-pi-zero board. Disable this node
by default and leave it to users to enable it if their board has
SPI NOR flash chip populated.

SPI NOR flash was optional in the first production batch in Dec 2016.
In later batches flash chip was pre-populated. However there should
be quite a few boards around which do not have flash chip.

The USB PHY can use either a GPIO pin or the PMIC's USB power supply
to sense VBUS. Since both options are available on the Cubietruck,
add the missing property for the USB power supply to the USB PHY node.

The device tree provides all usable options. Ultimately, which method
is used is up to the driver implementation.
