sunxi: mksunxiboot: Fix loading of files with a size which is not a multiple of 4

We should not be aligning the amount of bytes which we try to read from the
disk, this leads to trying to read more bytes then there are which fails.

file_size is already aligned to BLOCK_SIZE before being stored in
img.header.length, so there is no need for load_size at all.

sunxi: Remove mmc DMA support

The DMA code in sunxi_mmc.c is broken. mmc_trans_data_by_dma() allocates the
dma descriptors on the stack, and then exits while the dma transfer is in
progress, so the dma engine is reading stack memory which at that point may
be re-used. So far we've gotten away with this by luck, but recent u-boot
changes have shifted the stack start address by 16 bytes, which combined
with dma alignment now exposes this problem.

Since we end up just busy waiting for the dma engine anyway, this commit
fixes things by simply removing the dma code, resulting in smaller bug-free
code.

sunxi: Add sun4i support

Add support for the Allwinner A10 SoC also known as the Allwinner sun4i family,
and add the Cubieboard board which uses the A10 SoC.

Compared to sun7 only the DRAM controller is a bit different:
-Controller reset bits are inverted, but only for Rev. A
-Different hpcr values
-No MBUS on sun4i
-Various other initialization changes

sunxi: Add sun5i support

Add support for the Allwinner A13 and A10s SoCs also know as the Allwinner
sun5i family, and the A13-OLinuXinoM A13 based and r7-tv-dongle A10s based
boards.

The only differences compared to the already supported sun4i and sun7i
families are all in the DRAM controller initialization:

-Different hcpr values
-Different MBUS settings
-Some other small initialization changes

net: Rename and cleanup sunxi (Allwinner) emac driver

There have been 3 versions of the sunxi_emac support patch during its
development. Somehow version 2 ended up in upstream u-boot where as
the u-boot-sunxi git repo got version 3.

This bumps the version in upstream u-boot to version 3 of the patch:
- Initialize MII clock earlier so mii access to allow independent use
- Name change from WEMAC to EMAC to match mainline kernel & chip manual
- Cosmetic code cleanup

sunxi: Add support for using MII phy-s with the GMAC nic

(this will get used when we add these boards in a later patch).
