Most of the sun8i q8 boards have an SDIO wifi controller, on the
variants which use an USB wifi controller, this will result in a
couple of error msg-s in dmesg when proving the sdio bus and
an used mmc controller.

The best way to deal with wifi on this boards really is to simply
let the kernel auto-detect usb or sdio wifi controllers, so we
will just have to live with the few errors in dmesg.

This has been tested on a23 based q8 tablets with ESP8089, RTL8703AS and
RTL8189FTV wifi controllers.

Note currently the dts is pretty much empty (except for including the

this dts different from the pc-plus one, but that needs the h3 emac

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.

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.

Since commit 63a4cc24

, bio->bi_rw contains flags in the lower
portion and the op code in the higher portions. This means that
old code that relies on manually setting bi_rw is most likely
going to be broken. Instead of letting that brokeness linger,
rename the member, to force old and out-of-tree code to break
at compile time instead of at runtime.

No intended functional changes in this commit.

Commit abf54548

 changed it from an 'rw' flags type to the
newer ops based interface, but now we're effectively leaking
some bdev internals to the rest of the kernel. Since we only
care about whether it's a read or a write at that level, just
pass in a bool 'is_write' parameter instead.

Then we can also move op_is_write() and friends back under
CONFIG_BLOCK protection.

From the docs:
 "The usual behaviour of binfmt_misc is to spawn the binary lazily when
  the misc format file is invoked.  However, this doesn't work very well
  in the face of mount namespaces and changeroots, so the F mode opens
  the binary as soon as the emulation is installed and uses the opened
  image to spawn the emulator, meaning it is always available once
  installed, regardless of how the environment changes"
