Subject: [PATCH 02/12] fsi: Assign driver's bus in fsi_driver_register()

Instead of letting each driver assign the bus, do it once in the fsi
driver register function.

Simplify the fsi drivers that are living in drivers/fsi accordingly.

Once all fsi drivers dropped assigning the bus, fsi_bus_type can be made
a static variable.
