I tried to use arch_timer instead of .../omap-common/timer.c but it
was not straight forward. Just enabling CONFIG_SYS_ARCH_TIMER wouldn't
do the trick. Because of CONFIG_OMAP_COMMON we have automatically 
the omap timer built. Disabling CONFIG_OMAP_COMMON, however, breaks
the build.

So I couldn't go further.
