arm64: dts: imx93: update gpio node

Per binding doc, i.MX93 GPIO supports two interrupts and one register
base, compatible with i.MX8ULP. The current fsl,imx7ulp-gpio compatible
could work for i.MX93 in gpio-vf610.c driver, it is based on the base
address are splited into two with offset added in device tree node.

Now following hardware design, using one register base in device tree node.

This may break users who use compatible fsl,imx7ulp-gpio to enable
i.MX93 GPIO.
