* Set the I2C MUX bus selector in the i2cPresence functionRoland Veloz2019-01-301-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | - Expanded the i2cPresence API to take in the I2C MUX bus selector and the I2C MUX path. This will facilitate setting the bus selector within the i2cPresence function. - Set the I2C MUX bus selector in the i2cPresence function via the call to i2cAccessMux. - Simplified the i2cAccessMux API. It only takes in what it really uses. - Added several dump utility functions that are strictly there to dump certain data structures on an as needed basis. Was useful to have these utilities to see certain data structures but does not slow down the run time because the user must explicitly call them. - The structures that can get dumped are TARGETING::EepromVpdPrimaryInfo, eeprom_addr_t, TARGETING::FapiI2cControlInfo and I2C::misc_args_t.
