samus: exchange status with PD MCU on boot
On boot, the EC should send host command to exchange status with
PD MCU. This allows EC to get the correct input current limit
when EC reboots and PD does not.
Also had to move some of the charger state machine initialization
to run with HOOK_INIT so that it runs before the tasks run.
BUG=none
BRANCH=none
TEST=tested on EVT samus. Without this change, if you reboot
EC, and run charger command, the charger input current limit
is 512mA. with this change, when the EC reboots, it sends host
command to PD MCU to get current limit and sets it appropriately.
