chromeec: Add battery status event and re-enable _BIX

Hardware / Coreboot - Duncan Laurie [chromium.org] - 2 April 2015 10:27 UTC

Add a new host event to send a notify(0x80) to the battery when the EC indicates that battery status has changed.

The kernel has fixed the bug with _BIX method so it can be enabled now.
