omap2: twl-common: Add default power configuration

Commit Message

Matthias Brugger Jan. 23, 2013, 6:21 p.m. UTC

This patch adds a generic power script configuration.
When rebooting an OMAP3530 at 125 MHz, the reboot hangs.
With the generic power script, TWL4030 will be reset
when a warm reset occures. This way the OMAP3530 does not
hang on reboot.
