Allwinner DT64 changes for 4.16

There are two important changes in this round.

The first removes the redundant pinctrl setting for the MMC card detect
GPIO. We are moving to strict pinctrl/GPIO exclusion, i.e. GPIO usage
will block other pin muxing usage, and vice versa. The usage of pinmux
for guarding GPIO pins in the device tree prevents us from doing so.
This is part of an ongoing effort to clean up the existing device trees.

The other important change enables the PMIC on the Orangepi Win. The
PMIC provides power to most of the external onboard peripherals.
Enabling it will allow us to enable Ethernet or WiFi support later on.

The remaining changes in this round enable some peripheral, such as
Ethernet, an external WiFi chip, or LEDs.
