Our parent driver (clk-eyeq) now does the
device_set_of_node_from_dev(dev, dev->parent)
call through the newly introduced devm_auxiliary_device_create() helper.
Doing it again in the reset-eyeq probe would be redundant.
Drop both the WARN_ON() and the device_set_of_node_from_dev() call.
Also fix the following comment that talks about "our newfound OF node".

Declare the two reset domains found in the EyeQ6Lplus OLB and add
them to the data matched by 'mobileye,eyeq6lplus-olb' compatible.
Those reset domains are identical to those present in the EyeQ5
OLB, so no changes are needed to support them.
Also select reset-eyeq for all EYEQ SoCs instead of listing each one
individually, as it is needed by all Mobileye EyeQ SoC.

Make sure to drop the OF node reference taken when probing the auxiliary
device when the device is later unbound.

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.
