Glimmer: Support write first use day function
Only support write function.
BUG=chrome-os-partner:25145
BRANCH=glimmer
TEST=clean correspondence register to 0,
run "ectool batteryparam set 0 0x1234", and check the register.
The register change to 0x1234. Command "ectool batteryparam set 0 0x1234"
return 2 because we have no get function.
