The LCD backlight on the A23/A33 Q8 format tablets is enabled
with a GPIO controlled regulator, and brightness controlled with
the SoC's PWM controller.

The backlight is powered from the AXP223 PMIC's DC1SW output,
which is not supported yet. A proper bootloader is required
to enable it.

The brightness levels are arbitrary. The FEX files do not have
such information. As such, actual brightness levels may differ
from device to device.

This commits adds a generic dts file for q8 formfactor a13 based tablets.

The tablets ship in many variants, with the difference mainly being the
touchscreen controller / accelerometer / wifi chip used.

The wifi is USB based, and thus not listed in devicetree.

The touchscreen controller / accelerometer may turn out to be a problem
once we add support for those. We can either do something with devicetree
overlays, or add sun5i-a13-<touchscreen>-<accelerometer>.dts files. The
latter is what the android mod community is doing with firmware images.

This dts was tested with an a13 q8 tablet with a pcb labelled: "94V-0",
silead gsl1680 touchscreen controller and a mc32x0 accelerometer.

This is the sun5i / a13 version of sun8i-q8-common.dtsi for use in dts
files for a13 q8 based tablets. Compared to sun8i this uses uart1 for the
serial console, and PG0 for card-detect for mmc0.

This also adds pmic and otg support, which both use the same config on
all known q8 a13 devices. This is not present in sun5i-q8-common.dtsi
because pmic / otg support for sun8i has not yet been merged.
