Add const to bin_attribute structures as they are only passed to the
functions sysfs_{remove/create}_bin_file or
device_{remove/create}_bin_file. The arguments passed are of
type const, so declare the structures to be const.
Done using Coccinelle:

Same script was modified for device_{create/remove}_bin_file functions.
Cross compiled drivers/rtc/rtc-tx4939.o file for mips architecture.
