[PATCH 3/5] bcache: Move couple of string arrays to sysfs.c

[Coly Li <colyli@suse.de>]

From: Andy Shevchenko <andriy.shevchenko@linux.intel.com>

There is couple of string arrays that are used exclusively in sysfs.c.
Move it to there and make them static.

Besides above, it will allow further clean up.

No functional change intended.
