ARM: s3c64xx: make bus_type const

Browse Source 
Since commit d492cc2573 ("driver core: device.h: make struct bus_type
a const *"), the driver core can properly handle constant struct
bus_type, move the s3c6410_subsys variable to be a constant structure as
well, placing it into read-only memory which can not be modified at
runtime.
