Allow dynmic i2c device addresses and set up PMIC targets to do this
Depending on which vendor made a given OCMB the i2c device address
of the PMIC targets on the OCMB will be different. To account for this
we have added a new DYNAMIC_DEVICE_ADDRESS attribute. This attribute
is filled out on the PMIC target by looking at the SPD on parent
OCMB chip. This means that we must do presence detection on the OCMB
prior to the the PMIC targets. While doing i2c operations if a given
target has the DYNAMIC_DEVICE_ADDRESS we will use that over the devAddr
in the any complex i2c attribute for that target.
