Support reading from EECACHE during runtime
To support VPD accesses at runtime we had to add support to access
the information in the EECACHE section of pnor during runtime. To
do this we copy the contents of the EECACHE section into reserved
memory during the runtime setup steps of hostboot. Then when HBRT
is loaded we will process that EECACHE section and built up a map
that will allow read/write accesses to the eecache section just
like during the IPL.
