OMAP3: PM debug: allow runtime toggle of PM features
Allow enable/disable of low-power states during idle. To
enable low-power idle:
echo 1 > /debug/pm_debug/sleep_while_idle
to disable:
echo 0 > /debug/pm_debug/sleep_while_idle
Also allow enable/disable of OFF-mode. To enable:
echo 1 > /debug/pm_debug/enable_off_mode
to disable:
echo 0 > /debug/pm_debug/enable_off_mode
