[PATCH 1/3] ARM: OMAP: 32k counter: resolve sparse warnings

[Paul Walmsley <paul@pwsan.com>]

Commit 1fe97c8f6a1de67a5f56e029a818903d5bed8017 ("ARM: OMAP: Make OMAP
clocksource source selection using kernel param") results in a new warning
from sparse:

arch/arm/plat-omap/counter_32k.c:86:12: warning: symbol 'omap_init_clocksource_32k' was not declared. Should it be static?

Fix by adding a temporary header file, needed until the 32k counter
code is moved to drivers/.
arch/arm/plat-omap/include/plat/counter-32k.h can't be added due to
ARM CONFIG_ARCH_MULTIPLATFORM restrictions on the use of the "plat/"
include path shortcut.
