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.

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.

Remove the gpio related devicetree nodes as these are no longer required
with the move to a combined pinctrl/gpio driver.

This patch adds pinctrl nodes to the VIA VT8500 and Wondermedia SoC dtsi
files to support the pinctrl driver.

UART modules on Wondermedia SoCs are connected via a gated clock
source, rather than directly to the 24Mhz reference clock. While
uboot enables UART0 for debugging, other UART ports are unavailable
until the clock is enabled.

This patch checks that a valid clock is actually passed from devicetree,
enables the clock in probe. This change removes the fallback when a
clock was not specified as it doesn't apply any longer (and would only
work if the UART clock was already enabled).

DTSI files are updated for VT8500, WM8505 and WM8650.
