Arm Juno update for v5.18

Just a single update adding long waited support for SCMI firmware variant
as separate devicetrees. I wanted to deal with this differences in the
firmware interface within the bootloader for long time. But with variety
of bootloaders (u-boot, UEFI, ..etc) and need to add SCMI and SCPI
support for sake of discovery with discrepancies in shared memory layout,
it turned out difficult.

So, finally we are adding it as separate files so that we don't break
support for older SCPI firmware interface.
