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.
