64 always enable NUMA and
need memblock_add_node().
Replace add_memory_rigion(start, size, BOOT_MEM_RAM) with a weak function
which named mips_memblock_add. For Loongson64, override mips_memblock_add
at loongson64/numa.c. "memmap=" is similar to "mem=", replace it too.

Add loongson_kexec_prepare(), loongson_kexec_shutdown() and
loongson_kexec_crashdown() for passing the parameters of kexec_args.
To start loongson64, CPU0 needs 3 parameters:
fw_arg0: the number
y
CPUs in a querying loop.

Delete unused macro. Combine ipi_*_regs_init and mailbox_buf_init as
ipi_init to avoid redundant codes.

While it does make sense to allow CONFIG_NUMA and !CONFIG_SMP
in theory, it doesn't make much sense in practice. Follow other
architectures and make CONFIG_NUMA select CONFIG_SMP.

However, the round_down's second parameter must be a power of 2.
The author mean not align. So change it from 0 to 1.
