[PATCH] drm/i915: add const to bin_attribute

[PATCH] drm/i915: add const to bin_attribute

[Bhumika Goyal]

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 corresponding arguments are of
type const, so declare the structures to be const.
