Subject: [PATCH 2/3] MIPS: Cleanup code about plat_mem_setup()

In the current code, plat_mem_setup() is called by arch_mem_init() instead
of setup_arch() and has been declared in asm/bootinfo.h, so modify the code
comment to reflect the reality and remove the useless duplicate declartion
in arch/mips/kernel/setup.c.

Fixes: 2925aba4223f ("[MIPS] Cleanup memory management initialization.")
