*	Route scom operations on OCMB chips to fapi2 mmio scom interface	Christian Geddes	2018-11-19	1	-2/+2
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	After we get OMI targets trained we can communicate with the OCMB chips via MMIO. This includes reading and writing scom registers on the OCMB chip. This commit hooks up all of the plumming so when a HWP calls fapi2::getScom/putScom on an OCMB chip hostboot will be able to determine what functions to call to perform the operation.

*	Route scom operations on OCMB chips to exp_i2c_scom interface	Christian Geddes	2018-11-15	1	-0/+48
	Before we get OMI targets trained we must use i2c to access scom registers on the OCMB chip. This commit does all of the plumbing so when HWP calls getScom() on a OCMB target, the hostboot platform recognizes this as a special scom and routes it to a new i2scom DD. This device driver will truncate the scom address to 32 bits and run the exp_i2c_putscom/exp_i2c_getscom interfaces to perform the operation. Eventually we need to also support MMIO scoms to the OCMB chip, the MMIO scoms will be used after the OMI training is complete.
