[PATCH RESEND 0/2] gpio: add imx7ulp gpio support

[Dong Aisheng]

This is a rebased version against 4.13-rc2 Linus master branch with
latest ACKs collected.

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 FSL_GPIO_HAVE_PDDR with fsl_gpio_soc_data data
to distinguish this differences. And we support getting the output
status by checking the GPIO direction in PDDR.
