asm-m32r/uaccess.h must #include <asm/setup.h>

This patch fixes the following compile error caused by
commit 4016a139
(mm/nommu.c: return 0 from kobjsize with invalid objects):

/home/bunk/linux/kernel-2.6/git/linux-2.6/mm/nommu.c: In function 'kobjsize':
/home/bunk/linux/kernel-2.6/git/linux-2.6/mm/nommu.c:112: error: 'memory_end' undeclared (first use in this function)
/home/bunk/linux/kernel-2.6/git/linux-2.6/mm/nommu.c:112: error: (Each undeclared identifier is reported only once
/home/bunk/linux/kernel-2.6/git/linux-2.6/mm/nommu.c:112: error: for each function it appears in.)

The patch also removes now no longer required memory_{start,end}
declarations inside access_ok().
