m32r: mm: fix build warning 



While building we are getting warnings:

  arch/m32r/mm/init.c:63:17: warning: unused variable 'low'
  arch/m32r/mm/init.c:62:17: warning: unused variable 'max_dma'

max_dma and low are only used if CONFIG_MMU is defined.  Lets declare
the variables inside the #ifdef.
