EMC voltage for Mariko; Fix #60; Show battery & voltage info in overlay on Erista

Browse Source 
- From previous analysis, EMC voltage is set before AMS loads on Mariko, and will not be set again or changed afterwards.

- sys-clk-OC will take care of setting emc voltage on Mariko once it loads.

- OS will not hang at boot as it always boots with EMC @ 1600 MHz.
