hdata/memory: Add memory reservations to the DT
Currently we just add these to a list of pre-boot reserved regions
which is then converted into a the contents of the /reserved-memory/
node just before Skiboot jumps into the firmware kernel.
This approach is insufficent because we need to add the ibm,prd-instance
labels to the various hostboot reserved regions. To do this we want to
create these resevation nodes inside the HDAT parser rather than having
the mem_region flattening code handle it. On P8 systems Hostboot placed
its memory reservations under the /ibm,hostboot/ node and this patch
makes the HDAT parser do the same.
