There is DEVICE_ATTR mechanism in separate attribute define.
So this change is to use attr array, also use
sysfs_create_files in init function & sysfs_remove_files in
fini function.
This maybe make the code a bit readable.

Signed-off-by: Bernard Zhao <bernard@vivo.com>

Changes since V1:
*Use DEVICE_ATTR mechanism
