Subject: ARM: ICST: merge common ICST VCO structures

The structures for the ICST307 and ICST525 VCO devices are
identical, so merge them together.

Subject: ARM: ICST: icst.*_ps_to_vco() functions are unused, remove them

These functions were originally implemented for the CLCD driver before
we had clk API support.  Since the CLCD driver does not use these
anymore, we can remove them.

This makes the ICST support fit more nicely with the clk API,
eliminating the need to *1000 and /1000 in places.

From c5a0adb51002e51a4254cb7f0ab7190d41d8b930 Mon Sep 17 00:00:00 2001
From: Russell King <rmk+kernel@arm.linux.org.uk>
Date: Sat, 16 Jan 2010 20:16:10 +0000
Subject: ARM: ICST: kill duplicate icst code

The only difference between ICST307 and ICST525 are the two arrays
for calculating the S parameter; the code is now identical.  Merge
the two files and kill the duplicated code.
