The a23-ippo-q8h tablets have volume up/down buttons using the lradc. This
has been tested on both a v5 and a v1.2 tablet.

The pinctrl nodes require some extra opaque arguments for the pull up and drive
strength values.
Introduce a new header file and convert the device trees to replace these
opaque numbers by defines.

The Ippo q8h has its serial console connected to the r-uart. Adjust the
serial0 alias to match.
This fixes the kernel serial console no longer working since 3.19-rc1, because
8250_dw.c now honors dt aliases, causing the serial console to be ttyS5 rather
then being ttyS0, as it was in 3.18 and before.
Note that adjusting bootargs instead is not an acceptable fix, because
console=ttyS0,115200 is used by a lot of bootscripts, etc. and this should
continue to work.

The current GPL only licensing on the DTSI makes it very impractical for other
software components licensed under another license.
In order to make it easier for them to reuse our device trees, relicense our
device trees under a GPL/X11 dual-license.

i2c0 is connected to the gsl1680 capacitive touch panel controller.
i2c1 is connected to an mma7660 3-axis accelerometer.
i2c2 is connected to the front and back gc0309 camera sensors.
The camera sensors require additional regulators be enabled before
they are available.
All these peripherals are not supported by the kernel yet.

Now that we have R_PIO controller support and the pinmux for R_UART,
add the correct pinctrl properties to the R_UART node.

The Ippo-q8h is a tablet circuit board commonly found in cheap Android
tablets with A23 SoCs. There are at least 2 versions of the board, with
different peripherals, such as WiFi chips.
Common features among these tablets include 512 MB DRAM, NAND, MMC, LCD,
capacitive touchscreen, accelerometer, 1 or 2 camera sensors, USB OTG,
microphone and speaker.
v5 of these board designs has a ESP8089 WiFi chip (not supported)
connected to mmc1. This patch adds very basic support.
