platform/chrome: of_hw_prober: Support trackpad probing on Corsola family

Various MT8186 Corsola Chromebooks (squirtle, steelix and voltorb
families) have second source trackpads that need to be probed.
The power supply for these are always on and their reset/enable
lines are not exposed.

Add them to the probing list.
