[Crash-utility] [PATCH 2/3] mips: set section_size_bits and max_physmem_bits

[Rabin Vincent]

From: Rabin Vincent <rabinv at axis.com>

Enable SPARSEMEM support by setting this two values.  It's not clear to
me if they'll work on all MIPS platforms, but they do on the ones I have
access to and should provide reasonable defaults.
