Ben Dooks ec8292347b [ARM] S3C24XX: Fix nor-simtec driver sparse errors
Fix the following sparse errors in arch/arm/mach-s3c2410/nor-simtec.c:

53:27: warning: symbol 'simtec_nor_pdata' was not declared. Should it be static?
77:13: warning: symbol 'nor_simtec_init' was not declared. Should it be static?
