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 kernel parameter is specified. 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.
