This patch adds support for the MHU mailbox peripheral used on Juno by
application processors to communicate with remote SCP handling most of
the CPU/system power management. It also adds the SRAM reserving the
shared memory and SCPI message protocol using that shared memory.

Sorry for noticing this after the ACK, is there any reason why the scpi node is not inside
the juno-clocks.dtsi file?

Because SCPI is not just about clocks? Just happens that these first
patches are but there's thermal sensors and other things as well.
