Rediscover I2C Targets after Host I2C Reset
It's possible that some targets that use I2C to detect if they are
present might not be present after a system re-IPLs and performs a
FSI I2C Reset. Therefore, later in the IPL, after a Host I2C Reset
sequence an attempt to rediscover any of these targets is made.
If any new targets are found, the system will re-IPL. Currently
only supporting looking for DIMMs now on OpenPower systems with
securemode enabled.
