Lukas Wunner 44a45be57f sysfs: Unbreak the build around sysfs_bin_attr_simple_read() ...

Günter reports build breakage for m68k "m5208evb_defconfig" plus
CONFIG_BLK_DEV_INITRD=y caused by commit 66bc1a1733 ("treewide:
Use sysfs_bin_attr_simple_read() helper").

The defconfig disables CONFIG_SYSFS, so sysfs_bin_attr_simple_read()
is not compiled into the kernel.  But init/initramfs.c references
that function in the initializer of a struct bin_attribute.

Add an empty static inline to avoid the build breakage.
