exynos5: Use config_distro_bootcmd.h

This replaces the existing CONFIG_BOOTCOMMAND for exynos5250 and 5420.

exynos4 platforms seem to have existing complex extra env configuration for
booting and so are excluded here. Hence the bootcmd.h is added to
exynos5-common.h.

I have build tested on all exynos platforms (MAKEALL -s exynos), but only boot
tested on arndale.
