Pickup defines from pgtable-2level.h to make NOMMU build happy.

This needs more detail.

It comes from

  CC      arch/arm/kernel/setup.o
arch/arm/kernel/setup.c: In function 'reserve_crashkernel':
arch/arm/kernel/setup.c:1001:25: error: 'SECTION_SIZE' undeclared (first use in this function)
             crash_size, SECTION_SIZE);
                         ^
arch/arm/kernel/setup.c:1001:25: note: each undeclared identifier is reported only once for each function it appears in
make[1]: *** [arch/arm/kernel/setup.o] Error 1
make: *** [arch/arm/kernel] Error 2

Hmm, I decided not to use CRASH_ALIGN there because I didn't want to
break anyone's existing setup unnecessarily, however arguably it
should be CRASH_ALIGN to ensure that the new kernel is properly
positioned.

I wonder if we can get away with changing that, rather than
unnecessarily introducing these otherwise meaningless definitions
for R-class.
