Add new path in EEPROM device op to allow reading from new EECACHE
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.
