ARM: 5999/1: Including device.h and resource.h header files in linux/amba/bus.h

linux/amba/bus.h have dependencies on linux/device.h and linux/resource.h, but
it doesn't include them. We get compilation errors in our files which include
bus.h but doesn't include device.h and resource.h. This patch includes device.h
and resource.h in linux/amba/bus.h file.
