Subject: [PATCH 04/13] reset: eyeq: Add Mobileye EyeQ6Lplus OLB

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.
