Replace PIO readout with DMA when supported. This contains both a direct
DMA method and one using a bounce buffer. PIO is still the preferred fall-back.
Follow-up patches should implement both tx and the nand-component's
page access mode, in which hardware automatically validates the ECC checksum.

Following are two patches for sunxi nand DMA support. There's a whole phletora
of reasons why these are marked RFC, including:
- Sunxi DMA support still needs to be merged upstream
- Sun7i NAND definitions are not merged upstream
- No TX support
- Bounce buffer size is fixed to 8KB, and I have no
Oh yes, thanks for pointing this one out. I increased the malloc pool
during debugging as google hinted towards UBI being rather
memory-hungry, but forgot to double-check whether it was required. I
just did, and as it turns out it really only needs to be increased to
8MiB for UBI to work in my

V4 slightly clarifies the gating code and is a bit more precise with
definitions for other boards. As far as I'm concerned they can be merged
now.

The following patches take the work by Daniel Kochmánski, and make some
heavy modifications for readability and functionality, based on Boris
Brezillon's Linux driver. Tested on an Olimex Lime w/ A20.
Patches are sent as RFC. Open questions:
- Config options added are partially NAND-chip specific.
