This function can fail if the device tree runs out of space. Rather than
silently booting with an incomplete device tree, allow the failure to be
detected.
Unfortunately this involves changing a lot of places in the code. I have
not changed behvaiour to return an error where one is not currently
returned, to avoid unexpected breakage.
Eventually it would be nice to allow boards to register functions to be
called to update the device tree. This would avoid all the many functions
to do this. However it's not clear yet if this should be done using driver
model or with a linker list. This work is left for later.

Accessing powered down peripherals will hang the bus, so check power
domain status before initializing SATA and fixup the FDT to disable

Implement reset for highbank platform. Reset is triggered via a wfi
instruction, so enabling armv7 for the compiler is necessary.
