ec_commands: Add new EC_CMD_PD_CONTROL command
This commands makes it possible to control the PD chip (or
the interaction between EC and PD), from the AP.
- PD_SUSPEND: Suspends the PD chip: EC needs to stop talking
to PD chip. Useful at beginning of PD FW update.
- PD_RESUME: Resumes the PD chip: EC can start talking to PD
chip again. Useful at end of PD FW update.
- PD_RESET: Resets the PD chip (called at the end of the update).
- PD_CONTROL_DISABLE: Prevents further calls to this command
(for security reason, we do not want the AP to be able to
call the other subcommands after the update has been performed).
