chromeec: Add support for reading second battery info
We share the same shared memory fields for both batteries. When
the host wants to switch battery to read out, it will:
- Set BTID (EC_ACPI_MEM_BATTERY_INDEX) to the required index
- Wait for BITX (EC_MEMMAP_BATT_INDEX) to have the required value
- Then fetch the data
BRANCH=none
BUG=b:65697620
TEST=Boot lux, both /sys/class/power_supply/BAT0 and BAT1 are
present, data is valid.
