drivers: gpio: update gpio_mcux.c driver

update gpio driver to adapt rt7xx gpio model:
1. There is no PORT_Type on RT7xx,so set PORT_Type as void
2. Add port_no parameter in gpio_mcux_config to adapt IOPCTL driver
3. Add gpio-port-offest parameter in blinding, it will help map the
   relation between index n and gpio port when some soc have domain
   access attribution.
3. Splite gpio_mcux_configure function into two functions(
   gpio_mcux_iopctl_configure and gpio_mcux_port_configure)
   according to CONFIG_PINCTRL_NXP_IOCON macro
4. Add code to adapt RT700 GPIO attribute configuration
