Pull MIPS fixes from James Hogan:
 "A couple of MIPS fixes for 4.16-rc1, including an important regression
  in 4.15 and a rather more longstanding corner case build fix.

  These are separate from the main pull request as one of the bugs fixed
  was only recently introduced in v4.15-rc8.

   - Fix CPS regression on older binutils due to MIPS_ISA_LEVEL_RAW fix
     (4.15)

   - Fix allmodconfig + CONFIG_MACH_TX49XX=y builds due to incorrect use
     of IS_ENABLED() (2.6.28)"
