MIPS: Reserve nosave data for hibernation

MIPS: Reserve nosave data for hibernation

BugLink: http://bugs.launchpad.net/bugs/1590455
commit a95d069204e178f18476f5499abab0d0d9cbc32c upstream.

After commit 92923ca3aacef63c92d ("mm: meminit: only set page reserved
in the memblock region"), the MIPS hibernation is broken. Because pages
in nosave data section should be "reserved", but currently they aren't
set to "reserved" at initialization. This patch makes hibernation work
again.
