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.

Patched sysmodules would be persistent until pcv or ptm was updated in new HOS (normally in `x.0.0`).

1. Dump `prod.keys` with Lockpick_RCM
2. Dump HOS firmware with TegraExplorer
3. Configure and run `test_patch.sh` to generate patched pcv & ptm sysmodules in nca
4. Replace nca in `SYSTEM:/Contents/registered/` with TegraExplorer
5. `ValidateAcidSignature()` should be stubbed to allow unsigned sysmodules to load (a.k.a. `loader_patch`)
