[PATCH] Alchemy: remove unused get/set_au1x00_lcd_clock() functions.

Subject: [PATCH] Alchemy: remove unused get/set_au1x00_lcd_clock() functions.

Original-recipient: rfc822;linux-mips@linux-mips.org
Sender: linux-mips-bounce@linux-mips.org
User-agent: Mutt/1.5.16 (2007-06-09)
From: Manuel Lauss <mano@roarinelk.homelinux.net>

They don't do anything except print annoying messages,
and are not called from anywhere interesting.
