In preparation for sharing the "loading" and "data" sysfs nodes with the new firmware upload support, split out sysfs functionality from fallback.c and fallback.h into sysfs.c and sysfs.h. This includes the firmware class driver code that is associated with the sysfs files and the fw_fallback_config support for the timeout sysfs node. CONFIG_FW_LOADER_SYSFS is created and is selected by CONFIG_FW_LOADER_USER_HELPER in order to include sysfs.o in firmware_class-objs. This is mostly just a code reorganization. There are a few symbols that change in scope, and these can be identified by looking at the header file changes. A few white-space warnings from checkpatch are also addressed in this patch.
