Sansa Connect: Disable EMIF clock after booting main binary. Raise the threshold values for battery dangerous and shutoff levels.
On this player EMIF is needed for accessing NOR flash. Disabling it improves battery runtime by about 25 minutes. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@31373 a1c6a512-1295-4272-9138-f99709370657
