Thanks, please note that in case of the power role swap I started a discussion
with the EC team to verify the assumption we introduce here (the resp.role
populated by `cros_ec_cmd` should be equal to the target role if the operation
is successful). During testing I saw that the `resp.role` was not equal
to the target role but the role swap operation was successful (I
verified in sysfs
that the power role is the expected one).

In case they advise that our assumption is not correct we should remove the
assert resp.role == target_role for the power role.
