Add Mobileye EyeQ reset controller driver, for EyeQ5, EyeQ6L and EyeQ6H
SoCs. Instances belong to a shared register region called OLB and gets
spawned as auxiliary device to the platform driver for clock.
There is one OLB instance for EyeQ5 and EyeQ6L. There are seven OLB
instances on EyeQ6H; three have a reset controller embedded:
- West and east get handled by the same compatible.
- Acc (accelerator) is another one.
Each instance vary in the number and types of reset domains.
Instances with single domain expect a single cell, others two.
