MIPS: Avoid FP ELF checks when CONFIG_MIPS_FP_SUPPORT=n
When CONFIG_MIPS_FP_SUPPORT=n we don't support floating point, so we can avoid needless checks of ELF headers specifying the FP ABI or NaN encoding to use. Deselect CONFIG_ARCH_BINFMT_ELF_STATE in this case to avoid the need for our arch_elf_pt_proc() & arch_check_elf() functions, and stub out the mips_set_personality_nan() & mips_set_personality_fp() functions such that SET_PERSONALITY() doesn't need to worry about any of this.
