9efaca3e84 ahci: mmio_base is a virtual address
Don't store it in a u32.

Don't dereference the bus address as if it were a virtual address
(fixes 284231e49a ("ahci: Support splitting of read transactions
into multiple chunks")).

Fixes crash on boot in MPC8641HPCN_36BIT target.

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.

344ca0b40c ahci: convert to use libata functions and definitions
libata already has similar functions as implemented in the ahci code.
Refactor the code to use the libata variants and remove the dependency on
ata.h. Convert some defines to use the version from libata.h. Also, remove
some unnecessary memset's of bss data.

This is a step toward hopefully merging ahci.c and dw_ahsata.c which are
essentially the same driver.

4e422bce8a ahci: cosmetics and cleanup
- print the correct speed
- print all the AHCI capability flags
(information taken from Linux kernel driver)
- clean up some comments

For example, this might show the following string:
AHCI 0001.0300 32 slots 6 ports 6 Gbps 0x3 impl SATA mode

53677ef18e Big white-space cleanup.
This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).

Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.
