Sync the mx7ulp device tree related files with the one from
NXP U-Boot vendor tree (imx_v2019.04_4.19.35_1.0.0).

The mainline support for i.MX7ULP is very premature at this stage.

We should probably re-sync with mainline Linux dts when it gets
in better shape, but for now sync with the U-Boot vendor code.

These functions do not use driver model but are fairly widely used in
U-Boot. But it is not clear that they will use driver model anytime soon,
so we don't want to label them as 'legacy'.

Move them to a new irq_func.h header file. Avoid the name 'irq.h' since it
is widely used in U-Boot already.

Move this function header to serial.h since this function is clearly
