In the DB8500 Reference Manual SDI devices are described as being
part of peripheral blocks. This is more in line with how these devices
are actually represented in hardware, so here we detail which
peripheral block each of the SDI devices belong in the node name.

Here we add the Device Tree nodes which are required to successfully
probe the MMCI driver which will enable the four cards available on
ST-Ericsson's HREF hardware development platform.

Snowball's external SD/MMC slot is only capable of 4 bit data
transfer, not 8 bits as previously thought. This is a simple
fixup moving to the correct settings.

There are two main versions of the ST-Ericsson hardware reference board,
each with subtle differences. These versions are described in current
platform data as 'mop500' for HREF v1.1 & v2.0 and 'hrefv60+' for latter
incarnations. However, the boards have much in common, so this patch
creates a .dtsi (Device Tree Source Include) file which describes the
similarities between the two boards and individual 'hrefprev60' and
'hrefv60plus' .dts files which depict the differences.

In ux500 platform code we currently support a number of devices.
Two of these devices are fairly similar, but have key differences.
Early (pre-v60) HREFs and the more up-to-date versions (v60+), and
they both need to be supported by Device Tree. Here we apply a DT
source file for the earlier versions.

gpio-keys when booting with Device Tree enabled.

Most devices have now been successfully DT:ed and each supported
platform has its own Device Tree source file. Hence the majority
of the platform specific device registration calls can now be
successfully removed.
