ARM: digicolor: add minimal device tree description

cx92755.dtsi describes CX92755 on chip peripherals. cx92755_equinox.dts describes the Equinox evaluation board for the CX92755 SoC.

---
This is the only remaining part of the "ARM: Conexant Digicolor CX92755 SoC support" series. See v3 changelog at
http://article.gmane.org/gmane.linux.kernel/1865896.

v4:
* Rename conexant_equinox.dts to cx92755_equinox.dts which is closer to common practice (Olof Johansson)

* Add a syscon node; this is now required for the interrupt controller

* Decrease the registers range in the interrupt controller node to just the IC registers range. We now use syscon to access the global UC_IRQ_CONTROL register.

* Rename the interrupt controller node to "interrupt-controller" as per ePAPR

2.1.4

The digicolor interrupt controller driver now needs syscon.

Also, as per clocksource maintainer request, we now have a separate config symbol, CONFIG_DIGICOLOR_TIMER, for the digicolor timer.
