ABI: Update FSI path documentation
The paths added back in 4.13 weren't quite correct. The in reality the files documented lived under /sys/devices/../fsi0/rescan /sys/devices/../fsi0/break /sys/devices/../fsi0/slave@00:00/term /sys/devices/../fsi0/slave@00:00/raw In 5.5 with the addition of the FSI class they move to /sys/devices/../fsi-master/fsi0/rescan /sys/devices/../fsi-master/fsi0/break /sys/devices/../fsi-master/fsi0/slave@00:00/term /sys/devices/../fsi-master/fsi0/slave@00:00/raw This is closer to how the (incorrect) documentation described them.
