This switches the code using a local remapping of the
system controller to enable the U300 board to be
self-powered over to making the U300-specific syscon
compatible with the MFD generic syscon driver, selecting
the generic syscon driver, and augmenting the board
power code to pick the regmap and manipulate the syscon
from the regmap side of things.

This converts the last of the U300 clocks to being probed from
the device tree.

This moves the slow, fast, AHB bridge and "rest" clocks on
the U300 system controller over to registration from the
device tree.

This converts the fixed and fixed-factor clocks in the U300
platform to register themselves from the device tree.

This adds a device tree node for the U300 system controller
and remaps this dynamically instead of using hard-coded
virtual addresses. The board power set-up code is altered
to fetch a reference to the syscon using ampersand <&syscon>
notation. This way of passing a pointer to the syscon will
also be used by the clocks.

This registers the U300 FSMC flash controller from the
device tree, and defines the three partitions. Skip the
BBT scan as in the current platform data.

This probes the U300 dummy-spichip from the device tree
and adds the apropriate node to the tree.

This registers the PL022 PrimeCell from the U300 device
tree. We make a new copy of the platform data for the
device tree boot path, as the old platform data is in an
older file which will be going away.

This adds the COH 901 318 DMA controller to the U300
device tree. All devices now converted to device tree
so far will start to find their DMA channels.
Note that the U300 is not yet using the device tree
to obtain DMA channels, but this is a first step.

This adds DMA channel assignments to the MMC/SD-controller
and the two UARTs already in the U300 device tree, as we
have now defined a way to obtain DMA channels from the
device tree.

This adds support for the U300 MMC/SD card slot from the device
tree boot. No other changes needed.

Now that we have enabled board power and the AB3100 regulators,
put the regulator data into the device tree and enable it so
we can start to tie regulators to devices. To begin with we're
only supplying the power to the board itself.
