[PATCH v3] dt-bindings: gpio: Remove FSI domain ports on Tegra234

From: Prathamesh Shete <pshete at nvidia.com>

Ports S, T, U and V are in a separate controller that is part of the FSI
domain. Remove their definitions from the MAIN controller definitions to
get rid of the confusion.

This technically breaks ABI compatibility with old device trees. However
it doesn't cause issues in practice. The GPIO pins impacted by this are
used for non-critical functionality.
