arm64: dts: imx91-var-som-symphony: fix RGB_SEL handling

RGB_SEL is a board-level signal driven by the PCAL6408 GPIO expander on
the Symphony carrier board.

The signal needs to be driven high on the i.MX91 variant to keep the
board in the expected display configuration. Move the handling of this
line from a fixed regulator tied to the PCAL6408 supply to a GPIO hog on
the correct GPIO expander.
