The GPIO handle is referencing the wrong GPIO, so the voltage did not
actually change as intended. The pinmux is already correct, so just
correct the GPIO number.
Fixes: 4a13b3bec3b4 (arm64: dts: imx: add Zii Ultra board support)

Urgh, second fix for this regulator, it was really wrong in the
beginning. This time I actually measured the voltage on the board and
saw it changing as expected, so hopefully we are good now.
