Add exp_i2c_scom driver that will be consumed by HB/SBE platforms
This commit adds a new exp_i2c_scom.H file which contains two functions, i2c_get_scom and i2c_put_scom. These functions will take in a fapi2 OCMB target, an address and a buffer that either contains scom data to write or space for scom data to be written to. The functions use the fapi2::puti2c / fapi2::geti2c interfaces to perform the scoms.
