arm/dts: Add minimal device tree support for omap2420 and omap2430 Add minimal device tree support for omap2420 and omap2430. This is needed to keep the uart functional on omap2 after omap_serial_init is removed from board-generic.c.

ARM: dts: OMAP: Move interrupt-parent to the root node to avoid duplication The interrupt-parent attribute does not have to be added in each node since the fmwk will check for the parent as well to get it. Create an interrupt-parent for OMAP2, OMAP3, AM33xx and remove the attributes from every nodes that were using it.

ARM: dts: OMAP: Add timer nodes Add the 12 GP timers nodes present in OMAP2. Add the 12 GP timers nodes present in OMAP3. Add the 11 GP timers nodes present in OMAP4. Add the 7 GP timers nodes present in AM33xx. Add documentation for timer properties specific to OMAP. Thanks to Vaibhav Hiremath for creating the AM33xx timer nodes. I have modified Vaibhav's original nodes adding information on which timers support a PWM output. V5 changes: - Updated timer register sizes for OMAP2/3/4. - Modified AM335x timer register size to be 1KB instead of 4KB to align with HWMOD.
