Fix the following sparse errors in s3c24xx arch/arm directories:

arch/arm/mach-s3c2410/mach-amlm5900.c:168:13: warning: symbol 'amlm5900_map_io' was not declared. Should it be static?
arch/arm/mach-s3c2443/clock.c:397:12: warning: symbol 'clk_usb_bus_host' was not declared. Should it be static?

This patch makes these entries static.
