chromeec: Add command to override charger limit

Browse Source 
This patch adds EC_CMD_OVERRIDE_DEDICATED_CHARGER_LIMIT, which
overrides the max input current and voltage when a barrel jack
adapter supplies power.

BUG=b:64442692
BRANCH=none
TEST=Boot Fizz. Use chgsup console command to verify the max
current and voltage are set as expected.
