zephyr: Enable the chgramp task
This task is used to ramp up charging from an external source. Add
support for this along with required Kconfig options.
Add one more stub in system to make it build. This is covered by the
existing bug.
BUG=b:175434113
BRANCH=none
TEST=make BOARD=volteer -j30
build volteer on zephyr
So far the output is not interesting (need more drivers):
