Subject: Add I2C OCC support for P8 systems

P8 system uses I2C OCC and it uses different driver for occ-hwmon.
Add `--enable-i2c-occ` configure option to enable the support.

It searches i2c device names in sysfs to get all occ-hwmon devices and
use the i2c device name to bind/unbind the driver.

The occ control object path for I2C OCC hwmon becomes something like
/org/open_power/control/3_0050, where 3_0050 is the i2c address.
