WM8850 SoCs use a 24Mhz reference clock for the PLLs but the SoC file
currently parents all PLLs to the 25Mhz reference clock.
This patch corrects the PLL parent clock references.

Add support for the ARM, AHB, APB and DDR clocks found on the
WM8505, WM8650, WM8750 and WM8850 SoCs.
These clocks are gateable, but the enable part of the clock definition
is left out as there are no users for these clocks, and we don't want
them being disabled at boot, but it does provide users the ability to
check the current rate of these clocks.

Change the WM8850 SoC dtsi to use the new wm8850 specific PLL clock
binding. Previously, the WM8850 used the wm8750 pll clock which is
actually different to the wm8850 pll clock.

Missing aliases for uarts on vt8500, wm8505, wm8650 added.
Nodes incorrectly labelled uart@.., changed to serial@... on all SoCs.
Set each uarts default status = "disabled" as they generally don't exist.
For each board file, we only need to enable uart0 as no other uarts are
physically present on any of these boards.

vt8500, wm8650 and wm8850 have no cpu node specified.
wm8505 has a cpu node which contains an invalid compatible string, and
is missing the other required properties.

This is a rather large set of patches for device drivers that for one
reason or another the subsystem maintainer preferred to get merged
through the arm-soc tree. There are both new drivers as well as
existing drivers that are getting converted from platform-specific
code into standalone drivers using the appropriate subsystem
specific interfaces.
In particular, we can now have pinctrl, clk, clksource and irqchip
drivers in one file per driver, without the need to call into
platform specific interface, or to get called from platform specific
code, as long as all information about the hardware is provided
through a device tree.
Most of the drivers we touch this time are for clocksource. Since
now most of them are part of drivers/clocksource, I expect that we
won't have to touch these again from arm-soc and can let the
clocksource maintainers take care of these in the future.
Another larger part of this series is specific to the exynos platform,
which is seeing some significant effort in upstreaming and
modernization of its device drivers this time around, which
unfortunately is also the cause for the churn and a lot of the
merge conflicts.
There is one new subsystem that gets merged as part of this series:
the reset controller interface, which is a very simple interface
for taking devices on the SoC out of reset or back into reset.
Patches to use this interface on i.MX follow later in this merge
window, and we are going to have other platforms (at least tegra
and sirf) get converted in 3.11. This will let us get rid of
platform specific callbacks in a number of platform independent
device drivers.

Now that a display timing binding is available, convert our almost identical
binding to use the standard binding.
This patch converts the vt8500 and wm8505 framebuffer drivers and
associated dts/dtsi files to use the standard binding as defined in
bindings/video/display-timing.txt.
There are two side-effects of making this conversion:
1) The fb node should now be in the board file, rather than the soc file as
the display-timing node is a child of the fb node.
2) We still require a bits per pixel property to initialize the framebuffer
for the different lcd panels. Rather than including this as part of the
display timing, it is moved into the framebuffer node.
I have also taken the opportunity to alphabetise the includes of each
driver to avoid double-ups.
