davinci: add CPU idle driver
The patch adds support for DaVinci cpu idle driver.
Two idle states are defined:
1. Wait for interrupt
2. Wait for interrupt and DDR self-refresh (or power down)
Some DaVinci SoCs support putting DDR in self-refresh (eg Dm644x, DM6467)
while others support putting DDR in self-refresh and power down (eg DM35x,
DA8xx).
Putting DDR (or mDDR) in power down saves more power than self-refresh.
The patch has been tested on DA850/OMAP-L138 EVM.
