>From hardware perspective i.MX8ULP GPIO supports two interrupts,
1st for Trustzone non-secure irq, 2nd for Trustzone secure irq.
While i.MX7ULP GPIO only supports one interrupt, so i.MX8ULP is not
compatible with i.MX7ULP.
i.MX93 GPIO is directly derived from i.MX8ULP, so make i.MX93 compatible
with i.MX8ULP. i.MX95 GPIO is same as i.MX93, so also compatible with
i.MX8ULP
There maybe dtbs_check failure if only test the 1st patch. After
the patchset applied, no failure.
