MIPS: Fix some missing CONFIG_CPU_MIPSR6 #ifdefs

[ Upstream commit 4f33f6c5 ]

Commit be0c37c9 (MIPS: Rearrange PTE bits into fixed positions.)
defines fixed PTE bits for MIPS R2. Then, commit d7b63141
(MIPS: pgtable-bits: Fix XPA damage to R6 definitions.) adds the MIPS
R6 definitions in the same way as MIPS R2. But some R6 #ifdefs in the
later commit are missing, so in this patch I fix that.
