volteer: encode the keyboard backlight and numeric pad to fw_config

In order to support the keyboard backlight and numeric pad
switching, we need to encode the keyboard backlight and
numeric pad feature to the fw_config.

BUG=b:166707536
BRANCH=None
TEST=flash the ec.bin to the DUT and checked the keyboard function.
