Paul Burton	87321fddae	MIPS: Implement __arch_bitrev* using bitswap for MIPSr6 ... Release 6 of the MIPS architecture introduced the bitswap instruction, which reverses the bits within each byte of a word. Make use of this instruction to implement the __arch_bitrev* functions, which should be faster for most MIPSr6 CPUs, reduces code size slightly and allows us to avoid the lookup table used by the generic implementation, saving 256 bytes in the kernel binary by dropping that.
