Each pxa has an embedded OS Timers IP. The kernel cannot work without a
valid clocksource, and this adds the OS Timers to the pxa device-tree
description.

Add clocks to the IPs already described in the pxa device-tree
files. There are more clocks in the clock tree than IPs described in the
current pxa device-tree.
This patch ensures that :
- the current description is correct
- the clocks are actually claimed, so that clock framework doesn't
disable them automatically (unused clocks shutdown)

The gpio controller node inherited from pxa2xx.dtsi won't work for
pxa3xx SoCs, so let's override it in pxa3xx.dtsi.

This adds .dtsi files to describe the PXA SoCs. pxa3xx simply augments
pxa2xx. Not all devices are listed yet, and it will need some time to
get all the drivers ported.
For now, pxa27x.dtsi only enables the PXA's interrupt priority feature.
