Dong Aisheng 659d8a6231 gpio: vf610: add imx7ulp support ...

The Rapid General-Purpose Input and Output with 2 Ports (RGPIO2P)
on MX7ULP is similar to GPIO on Vibrid. But unlike Vibrid, the
RGPIO2P has an extra Port Data Direction Register (PDDR) used
to configure the individual port pins for input or output.

We introduce a bool have_paddr with fsl_gpio_soc_data data
to distinguish this differences. And we support getting the output
status by checking the GPIO direction in PDDR.
