[U-Boot] [PATCH] common.h: Add prototype of arch_preboot_os

[Nobuhiro Iwamatsu]

When we used arch_preboot_os() function because prototype of this is not
declared, following warning is output.

-----
warning: function declaration isn't a prototype [-Wstrict-prototypes]
-----

This adds prototype of arch_preboot_os() to include/common.h.
