Subject: [PATCH] auxdisplay: Remove unused functions

From: "Dr. David Alan Gilbert" <linux@...blig.org>

cfag12864b_getrate() and cfag12864b_isenabled() were both added
in commit 70e840499aae ("[PATCH] drivers: add LCD support")
but never used.

Remove them.

Signed-off-by: Dr. David Alan Gilbert <linux@...blig.org>
