treewide: Use sysfs_bin_attr_simple_read() helper
Deduplicate ->read() callbacks of bin_attributes which are backed by a
simple buffer in memory:
Use the newly introduced sysfs_bin_attr_simple_read() helper instead,
either by referencing it directly or by declaring such bin_attributes
with BIN_ATTR_SIMPLE_RO() or BIN_ATTR_SIMPLE_ADMIN_RO().
Aside from a reduction of LoC, this shaves off a few bytes from vmlinux
(304 bytes on an x86_64 allyesconfig).
No functional change intended.
