a6e50a88d8 ahci: provide sunxi SATA driver using AHCI platform framework
This enables the necessary clocks, in AHB0 and in PLL6_CFG. This is done
for sun7i only since I don't have access to any other sunxi platforms
with sata included.

The PHY setup is derived from the Alwinner releases and Linux, but is mostly
undocumented.

The Allwinner AHCI controller also requires some magic (and, again,
undocumented) DMA initialisation when starting a port.  This is added under a
suitable ifdef.

This option is enabled for Cubieboard, Cubieboard2 and Cubietruck based on
contents of Linux DTS files, including SATA power pin config taken from the
DTS. All build tested, but runtime tested on Cubieboard2 and Cubietruck only.

ae5de5a19d sunxi: Fix reset hang on sun5i
Do the same as the Linux kernel does, this fixes the SoC hanging on reset
about 50% of the time.

6620377e4b sunxi: Add i2c support
Add support for the i2c controller found on all Allwinner sunxi SoCs,
this is the same controller as found on the Marvell orion5x and kirkwood
SoC families, with a slightly different register layout, so this patch uses
the existing mvtwsi code.

f84269c5c0 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

745325a97d 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

643cf0ea02 sunxi: add sun7i clocks and timer support.
This patch adds the basic clocks and timer support for the Allwinner A20
(sun7i) processor. This code will not been compiled until the build is hooked
up in a later patch. It has been split out to keep the patches manageable.

Some of the code here is common to multiple sunxi subarchtectures, hence files
are named sun4i which is the earliest similar variant.
