d00bb8addc mips: intreadwrite: Only execute that code for mips r1 or r2
MIPS R6 supports unaligned memory access and does not have
the load/store-left/right family of instructions.

6766169c41 mips: intreadwrite: fix inline asm for gcc 4.8
Just like gcc 4.6 and later on ARM, gcc 4.8 on MIPS generates
inefficient code when a known-unaligned location is used as a
memory input operand.  This applies the same fix as has been
previously done to the ARM version of the code.

b82b49a5b7 mips: intreadwrite: remove unnecessary inline asm
GCC actually handles unaligned accesses correctly in all cases
except, absurdly, 32-bit loads on mips64.  The remaining asm is
thus not needed, and removing it results in better code.
