MIPS: Kconfig: Don't allow both microMIPS and SmartMIPS to be selected.
microMIPS and SmartMIPS can't be used together. This fixes the
following build problem:
Warning: the 32-bit microMIPS architecture does not support the `smartmips' extension
arch/mips/kernel/entry.S:90: Error: unrecognized opcode `mtlhx $24'
[...]
arch/mips/kernel/entry.S:109: Error: unrecognized opcode `mtlhx $24'
