omap: Fix DEBUG_LL uart to access phys addr when MMU isn't enable

Now we use a memory address to store the debug port info, So we need
to read/write this address when we choose DEBUG_LL. When MMU isn't
enable(I.E. the begining part of init stage of the linux kernel boot),
we need to access physical address instead of virtual address,
otherwise the kernel will crash.
