charge_manager: Add EC_CMD_OVERRIDE_DEDICATED_CHARGER_LIMIT
Usually, the max current and supply voltage of dedicated chargers
are not known to the EC.
This patch adds EC_CMD_OVERRIDE_DEDICATED_CHARGER_LIMIT, which
allows the host to change the max current and supply voltage of the
dedicated charge port.
BUG=b:64442692
BRANCH=none
TEST=make runtests && buildall. Boot Fizz and let coreboot set
the adapter current and voltage.
