Reserve correct range for Hostboot runtime data
Reserve correct range for Hostboot runtime data

All of the Hostboot reserved memory must be included inside the
initial "hb-rsv-mem" section.  Our move of the Hostboot HRMOR
from 128MB (0x8000000) to 4GB-256MB (0xF0000000) exposed a bug
in how we calculated the area.

Note that this current change does not correctly reserve the
data that lives below the HRMOR, which is required for MPIPL
to work.  However, the plan is to move this data into the upper
256MB range before that matters.
