akemi: enable ec feature flag override function
Akemi supports keyboard backlight by default, but the
new SKU does not support keyboard backlight.
We need to increase sku_id to distinguish whether
keyboard backlight is supported. So, enable ec feature
flag override to report keyboard backlight feature by sku_id.
BUG=b:144815890
BRANCH=master
TEST=Boot akemi boards, press Alt+Brightness-Up/Down to change
keyboard backlight, it has no function on sku_id=1/2, and it
works fine on sku_id=3/4.
