[PATCH] clocksource: sh_cmt: 32-bit control register access prototype

[Magnus Damm <magnus.damm@gmail.com>]

From: Magnus Damm <damm@opensource.se>

This is a 32-bit control register access prototype
for the CMT driver. It is not ready for merge but
it intends to show the reasoning behind the
register access patches included in this series:
"[PATCH 00/08] clocksource: sh_cmt: CMT driver update"
