[PATCH 1/5] dt-bindings: gpio: vf610: correct i.MX8ULP and i.MX93 interrupts

From: Peng Fan <peng.fan at nxp.com>

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

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