Can we please get a few MIPS defconfigs added to the 0-day testing?

- malta_kvm_defconfig
  this probably doesn't need to be a high priority build, but other
  configs don't yet cover MIPS KVM so its worth having (that bit us
  recently with 3.12 and 4.4 stable branches).

- 64r6el_defconfig and 32r2_defconfig (4.9 and later)
  these are just a couple of the new generic/multiplatform kernel
  configurations added in 4.9 (Paul Burton Cc'd). There are others too,
  but these will probably give decent coverage. These are likely to be
  increasingly relevant as more/new platforms are converted to use it.
  (note, the r6 one may require a newish toolchain).

Thanks
James
