ec/lenovo/h8: Make dock init in ramstage fully mainboard-specific

Discussed in CB:36093, in the past many lenovo boards need to declare
an empty h8_mainboard_init_dock() to satisfy h8.c.

Now the confusing H8_DOCK_EARLY_INIT might be retired, and if a
mainboard needs dock init (done with h8_mainboard_init_dock() in the
past) in ramstage, (discussed in CB:4294 where H8_DOCK_EARLY_INIT is
introduced) it can just do it in its own chip_ops.enable_dev function.

Tested on X200. Testing on other affected targets may be necessary.
