Modified Files:
        src/sys/arch/arm/samsung: exynos4_reg.h exynos5_reg.h exynos_gpio.c
            exynos_io.c exynos_soc.c
        src/sys/arch/evbarm/odroid: odroid_machdep.c

Log Message:
Revisit gpio and revisit register file mapping. The additional register files
are now mapped behind the origional register file.

The gpio channel GPZ is mapped over I2S0 in the separate audio register file
and were both abusively mapped over I2C0 in the main register file!

While here, delay the gpio bootstrap till on attachment. We could hasten it in
the odroid_machdep.c if needed. Also make the gpio code more resilliant and
allow booting correctly without any GPIO bits defined/available.
