With the original patch I only tried to reduce the number of compilation
failures. I encounter a lot. I'm no expert and I can only try to fix little
things such as this one.

I belive some people (like myself) would be confused by an empty menu and
would not immediately remember the SYS_ARCH_TIMER in a completely different
part of menuconfig.


I tried to find configs with both CONFIG_SYS_ARCH_TIMER and CONFIG_TIMER
enabled amd I couldn't find any. So it's probably OK to leave the patch as it
is and exceptions, if needed, can be added later.

PS: I saw your other patches that add dependencies on platform type.
    Nice work, really needed!
