Read HW Key Hash From SBE Seeprom via ChipOp when applicable
This commit uses SBEIO ChipOps to read the HW Key Hash from the
SBE Seeprom when reading from the Seeprom that booted the processor.
This will help avoid I2C collisions when both Hostboot and the SBE
try to access the same SBE Seeprom at the same time.
