Battery: Add command to export display SoC
Currently, CrOS EC passes the battery remaining capacity (mAh) and the
full capacity (mAh) through ACPI to the AP so that the host can
calculate the battery SoC.
The host further manipulates the SoC to get the display SoC, which is
used to determine user visible behaviors. To get consistent behaviors
in all power states, this change enables the EC to send the display
SoC to the host via EC_CMD_DISPLAY_SOC command.
The Powerd's part is I5bd1371f2569d21d55df1b50a3d709b98bbf0325.
