r329104 imported 4.15 DTS which brought CCU to a10/a20. In the process, they
swapped the ordering of 'clocks' for allwinner,sun4i-a10-ahci on both
sun4i-a10 and sun7i-a20 from PLL, Gate to Gate, PLL.
Swap it in the driver.
Name each ahci driver uniquely.
This remove the warning printed at each arm boot :
module_register: cannot register simplebus/ahci from kernel; already loaded from kernel
attachment code for various SOCs and busses. Remove all the static and
should-have-been-static and named-differently instances of it.
This should eliminate the recently-grown build warnings about multiple
definitions when building arm kernels.
In some cases, the driver must handle given properties located in
specific OF subnode. Instead of creating duplicate set of function, add
'node' as argument to existing functions, defaulting it to device OF node.
MFC after: 3 weeks
configuration from the FDT data, then set the pins into the requested
state. As part of this the gpio controller now reports the correct number
of pins instead of returning the number of bank * 32.
To allow for a future consolidated kernel we add the SOC_ALLWINNER_A10 and
SOC_ALLWINNER_A20 kernel options. These need to be set as appropriate for
the SoC the kernel will boot on.

The Allwinner SoC has an AHCI device on its internal main bus rather
than the PCI bus. This SoC is somewhat underdocumented, and its SATA
controller is no exception. The methods to support this chip were
harvested from the Linux Allwinner SDK, and then constants invented to
describe what's going on based on low-level constants contained in the
SATA standard and guess work.
This SoC requires a specific AHCI channel setup in order to start the
operations on the channel properly.
Clock setup and AHCI channel setup idea came from NetBSD.
Tested on Cubieboard 2 and Banana pi (and attachment on Cubieboard by
Pratik Singhal).
