The inet-d978_rev2 is a pcb used in generic A33 based tablets. It features
volume buttons, micro-usb otg, headphone connector and a power button.

On the board a Realtek RTL8723BS SDIO Wi-Fi module are soldered, and there
is also a accompanied board which has a Goodix GT9271 soldered.

As this board is desired to create tablets with a Home key dealed by
GT9271, a LED is present at the front panel at the position of the
Home key.

The R_PIO device node is missing #interrupt-cells, which causes
interrupt parsing to fail to match it as a valid interrupt controller.

Add #interrupt-cells to it. Also remove the unnecesary #address-cells
and #size-cells.

Rename the reference-design-tablet touchscreen node from gsl1680 to
touchscreen, all? tablets seem to use the same power and interrupt
gpio-s, but not all tablets use a gsl1680 controller making the
gsl1680 name somewhat misleading.

Also move the reg and compatible property to the actual tablet dts
as they may differ per tablet.

Add a dts file for the Empire Electronix M712 tablet, this is a 7" A13
tablet, with micro-usb (otg), headphone and micro-sd slots on the
outside. It uses a Goodix gt811 touchscreen controller, a RTL8188CTV
wifi chip and a DMART06 (1238a4) accelerometer.

Note currently the dts for this is somewhat empty. This will change
once we add support for the touchscreen and accelerometer.

A23/A33 has a NAND controller which can now be used properly.

Add a device node for it.

The DMA function cannot work because of changed DMA IP block, so it's
temporarily removed in the device node. However, with PIO mode it can still
work.

Tested on an Aoson M751s tablet with Boris Brezillon's "mtd: nand: allow
vendor specific detection/initialization" patchset, which is needed for the
large-block MLC chip to be recognized correctly.
