drivers: gpio: gpio_mcux: Fix port index mismatch issue

When GPIO works with IOPCTL, the PIO instance offset in IOPCTL
can't be calculated easily. It should be recorded in DTS based on
SOC integration.
When IOPCTL is used, add PIO reigster address in DTS, gpio_mcux
driver will configure the PIO register based on this address.
