dt-bindings: gpio: vf610: correct i.MX8ULP and i.MX93 



i.MX8ULP and i.MX93 actually has two interrupts for each gpio
controller, one for Trustzone non-secure world, one for secure world.

And they has one register based, not two as i.MX7ULP or VF610.

Although the Linux Kernel driver gpio-vf610.c could work with
fsl,imx7ulp-gpio compatible, it is based on some tricks did in
device tree with some offset added to base address.

So actually i.MX8ULP/i.MX93 is not compatible with i.MX7ULP.

Last, i.MX93 is directly derived from i.MX8ULP, so make i.MX93 GPIO
compatible with i.MX8ULP
