ec/lenovo/h8: Reintroduce h8_mb_init() for specific boards
Mainboard specific dock-init mechanism introduced
https://review.coreboot.org/c/coreboot/+/36093 works on most boards,
but https://ticket.coreboot.org/issues/256 shows that some boards
(e.g. x201 and t410) need communication with h8 EC to enable or
disable dock, (in dock_connect() and dock_disconnect() respectively)
so they must be done after the h8 EC is brought up, which is not
garanteed in the above mainboard specific dock-init mechanism.
This time, a hook function h8_mb_init() will be called at the end of
h8_enable(). (in place of the ancient h8_mainboard_init_dock() removed
in CB:36093) Its default implementation is a weak empty function, but
could be overrided with a strong one for boards needing to perform
actions which should be done after h8 EC is brought up.
This should fix the regression detected in
https://ticket.coreboot.org/issues/256
