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.

The Vybrid SoC device tree (vf610.dtsi) used this bindings since
its initial commit in May 2013. However, a proper gpiolib driver
was missing so far. With the addition of the gpiolib driver,
the bindings proved to be useful and complete, hence a good time
to add the documentation.
