ARM: sa1100: make match function take a const pointer

In commit d69d80484598 ("driver core: have match() callback in struct
bus_type take a const *"), the match callback for busses was changed to
take a const pointer to struct device_driver. Unfortunately I missed
fixing up the sa1111 code, and was only noticed after-the-fact by the
kernel test robot. Resolve this issue by properly changing the
sa111_match() function.
