This is a significant rework of the low-level clock, PLL and Power
Sleep Controller (PSC) implementation for the DaVinci family. The
primary goal is to have better modeling if the hardware clocks and
features with the aim of DVFS functionality.
Highlights:
- model PLLs and all PLL-derived clocks
- model parent/child relationships of PLLs and clocks
- convert to new clkdev layer
- view clock frequency and refcount via /proc/davinci_clocks
Special thanks to significant contributions and testing by David
Brownell.

Add base kernel support for the TI DaVinci platform.
This patch only includes interrupts, timers, CPU identification,
serial support and basic power and sleep controller init. More
drivers to come.
