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.

Add the missing devicetree nodes for PLL's found on the WM8505, WM8650
and WM8850 SoCs.

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.

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.

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.
