Support openpower-specific I2C device callouts

This change supports the openpower path for adding I2C device
callouts to error logs. The process works as follows:
- Create an I2C device lookup table on first use of I2C callout
- Use that table to map I2C info to the actual device to callout
- Callout any other I2C devices on the bus with lesser priority
- If no I2C match found, callout the I2C master instead
- If an I2C device was found, callout the I2C master as low
