MLK-17491-11 dt-bindings: gpio-vf610: add missing imx7ulp binding doc support
The Rapid General-Purpose Input and Output with 2 Ports (RGPIO2P) on MX7ULP is similar to GPIO on Vibrid, except it has an extra Port Data Direction Register (PDDR) used to configure the individual port pins for input or output.

Required properties for GPIO node:
-- compatible : Should be "fsl,<soc>-gpio", currently "fsl,vf610-gpio"
+- compatible : Should be "fsl,<soc>-gpio", below is supported list:

- reg : The first reg tuple represents the PORT module, the second tuple
the GPIO module.
- interrupts : Should be the port interrupt shared by all 32 pins.
