[PATCH 5/6] MIPS: CONFIG_MIPS_MT_SMP should depend upon CPU_MIPSR2

[Paul Burton]

The MT ASE cannot be used with CPUs that implement older releases of the
MIPS architecture than release 2, and is replaced in release 6. Encode
these constraints in Kconfig to ensure that MT code is only built as
part of kernels targeting an appropriate revision of the architecture.
