ec/starlabs: Add standardised ITE EC support

Add EC support that supports different Q Events and EC memory.
Created from the ITE IT5570E and IT8987E datasheets, all using
data port 0x4e.

Tested with Ubuntu 20.04.3 and Windows 10 on:

* StarBook Mk V (TGL + IT5570E):
*  ITE Firmware 1.00
*  Merlin Firmware 1.00

* LabTop Mk IV (CML + IT8987E):
*  ITE Firmware 1.04

* LabTop Mk III (KBL + IT8987E):
*  ITE Firmware 3.12
