[PATCH 3/3] ARM: OMAP: SRAM: resolve sparse warnings

[Paul Walmsley <paul@pwsan.com>]

Commit bb77209432873214a796a70a4539e4ebdf3feb54 ("ARM: OMAP: Move
omap2+ specific parts of sram.c to mach-omap2") adds some new sparse
warnings:

arch/arm/plat-omap/sram.c:43:6: warning: symbol 'omap_sram_push_address' was not declared. Should it be static?
arch/arm/plat-omap/sram.c:65:6: warning: symbol 'omap_sram_reset' was not declared. Should it be static?
arch/arm/plat-omap/sram.c:73:13: warning: symbol 'omap_map_sram' was not declared. Should it be static?

Fix by creating a temporary header file containing prototypes for
these SRAM functions - needed until the SRAM code is moved to
drivers/.  arch/arm/plat-omap/include/plat/sram.h can't be added due
to ARM CONFIG_ARCH_MULTIPLATFORM restrictions on the use of the "plat/"
include path shortcut.
