imxrt117x: add functions to control gpio

[gerard5]

Adds functions, similar to imxrt10xx API, which allow to configure, gpio direction and control gpio: get, set, clear gpio value, either single bit or whole register.

The goal is abbility to provide project plo_custom.c, e.g:

#include "imxrt.h"

void hal_customInit(void)
{
    /* deassert /RESET of other device */
    _imxrt_setIOmux(pctl_mux_gpio_sd_b1_00, 0, 10);
    _imxrt_setIOpad(pctl_pad_gpio_sd_b1_00, 0, 0, 0, 0, 0, 0);
    _imxrt_gpioConfig(gpio10, 3, 1);
    _imxrt_gpioSet(gpio10, 3, 0);
}
