davinci: Add base address and timer flexibility
The davinci timer code currently hardcodes the timer register base addresses, the timer irq numbers, and the timers to use for clock events and clocksource. This won't work for some a new SoC so put those values into the soc_info structure and set them up in the SoC-specific files. Signed-off-by: Mark A.
