firmware: arm_ffa: Declare ffa_bus_type structure in the header

smatch reports: drivers/firmware/arm_ffa/bus.c:108:17: warning: symbol 'ffa_bus_type' was not declared. Should it be static? ffa_bus_type is exported to be useful in the FF-A driver. So this warning is not correct. However, declaring the ffa_bus_type structure in the header like many other bus_types do already removes this warning. So let us just do the same and get rid of the warning. Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Sudeep Holla <[email protected]>
