Subject: [PATCH 08/12] mips: Dump memblock regions for debugging

It is useful to have the whole memblock memory space printed to console
when basic memlock initializations are done. It can be performed by
ready-to-use method memblock_dump_all(), which prints the available
and reserved memory spaces if MEMBLOCK_DEBUG config is enabled.
Lets call it at the very end of arch_mem_init() function, when
all memblock memory and reserved regions are defined, but before
any serious allocation is performed.
