MIPS: Reserve nosave data for hibernation
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.
