[PATCH] power: add const to bin_attribute structures

[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 parameters
passed are of type const, so declare the structures to be const.

Done using Coccinelle:

@m disable optional_qualifier@
identifier s;
position p;
@@
static struct bin_attribute s@p={...};

@okay1@
position p;
identifier m.s;
@@
(
sysfs_create_bin_file(...,&s@p,...)
|
sysfs_remove_bin_file(...,&s@p,...)
)

@bad@
position p!={m.p,okay1.p};
identifier m.s;
@@
s@p

@change depends on !bad disable optional_qualifier@
identifier m.s;
@@
static
+const
struct bin_attribute s={...};

Same script was modified for device_{create/remove}_bin_file functions.
