ARM: OMAP: fix new sparse warnings

[Paul Walmsley]

Commit e54adb1e79762d3591459e5b0e9b9ff578e33fdb ("ARM: OMAP: omap3evm:
cleanup revision bits") adds a new sparse[1] warning:

arch/arm/mach-omap2/board-omap3evm.c:90:4: warning: symbol 'get_omap3_evm_rev' was not declared. Should it be static?

This symbol no longer appears to be used outside this file, so mark it
static and remove the export.

Commit 801475ccb2b2c1928b22aec4b9e5285d9e347602 ("ARM: OMAP: move
debug_card_init() function") results in the following new sparse[1]
warning:

arch/arm/plat-omap/debug-devices.c:71:12: warning: symbol 'debug_card_init' was not declared. Should it be static?

Fix by including the proper header file.
