MIPS: mm: Fix definition of R6 cache instruction
Commit a168b8f1cde6 ("MIPS: mm: Add MIPS R6 instruction encodings") added an incorrect definition of the redefined MIPSr6 cache instruction. Executing any kernel code including this instuction results in a reserved instruction exception and kernel panic. Fix the instruction definition.
