Subject: [PATCH] Change HSBP FRU address and add MUX mode configuration
Changed the HSBP EEPROM FRU address according to Hardware
rework and added the MUX idle mode configuration as
"Disconnect". The later will keep MUX channel mode in
disconnected state after the channel is accessed.
Tested:
1. Detected and read the HSBP EEPROM FRU with new address
on reworked board.
2. Confirmed the idle state of MUX channel after it is
accessed is disconnected, this solved the bad read
caused by reading multiple buses of different MUXes at
same time.
