I didn't push this file to upstream Linux because didn't push any versal 
specific dtsi file there yet. But this file is just IDs which are used 
by power domain driver which is upstream already.

Here you can see support for xlnx,versal-firmware driver.
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/firmware/xilinx/zynqmp.c?h=v5.16-rc3#n1493

Here you can see full structure used on versal.
