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.

While parsing the EEPROMs of the system as part of the EECACHE process
if we detect a part has been replaced, removed, or added then we must
call markTargetChanged to notify hwas to take appropriate actions.
This commit also introduces the new preloaded EECACHE section for simics.

There are certain scenarios where we might want to update the
table of contents at the start of the EECACHE section in pnor to
indicate we have decided that the cached copy of one of the eeproms
is no longer valid. This commit adds the ability to mark a cache
entry as either valid or invalid by calling setIsValidCacheEntry
in the EEPROM namespace and tests to verify this works. Future commits
will add this call to places it is needed.

If the user passes a nullptr as the io_buffer it is assumed that
they want the size of the eeprom they are looking up. So just
return the size in io_buflen. This commit also adds useful debug
traces to the eepromdd.C file.

Recently a new EECACHE section was introduced to Hostboot. This section
gets populated with a copy of every PRIMARY_VPD eeprom (someday could
contain other eeprom roles also) during host_discover_targets. This
commit add support to allow users to select where they want to perform
their EEPROM device operation. If they pass CACHE to the deviceOp macro
then a read will come from the pnor cache, writes will write to pnor
cache and then also write to the eeprom HW. If HARDWARE is passed in
then reads and writes will be directly done on the eeprom hardware.
If AUTOSELECT is passed the code will check our cache to see if we have
a copy of the eeprom in question, if we have a copy we will go the
CACHE path, if no copy exists we will go the HARDWARE path. Along with
this change some reorganization was done w/ the eeprom related files.
