This patch removes all unused static iomapping from
exynos4/5_iodesc table, and at the same time removes
related macros from map.h and map-s5p.h.
All such mappings are present in exynos.c but not currently
there are no users of these mappings, so its safe to remove these.

This patch has been compiled tested for exynos_defconfig; multi_v7_defconfig;
s5pv210_defconfig; s3c6400_defconfig; and s3c2410_defconfig.

I have verified system booting on SMDK5250 and Exynos3250 based board.

May be I am missing something here, but I can't see this in any branch of
your tree.

Thanks,
