arch, mm: remove arch specific show_mem

We have a generic implementation for quite some time already.  If there
is any arch specific information to be printed then we should add a
callback called from the generic code rather than duplicate the whole
show_mem.

The current code has resulted in the code duplication and the output
divergence which is both confusing and adds maintainance costs.

Let's just get rid of this mess.
