Paul Burton 6a6cba1d94 MIPS: Fix CM region target definitions ... The default CM target field in the GCR_BASE register is encoded with 0 meaning memory & 1 being reserved. However the definitions we use for those bits effectively get these two values backwards - likely because they were copied from the definitions for the CM regions where the target is encoded differently. This results in use setting up GCR_BASE with the reserved target value by default, rather than targeting memory as intended. Although we currently seem to get away with this it's not a great idea to rely upon. Fix this by changing our macros to match the documentated target values. The incorrect encoding became used as of commit 9f98f3dd0c ("MIPS: Add generic CM probe & access code") in the Linux v3.15 cycle, and was likely carried forwards from older but unused code introduced by commit 39b8d52542 ("[MIPS] Add support for MIPS CMP platform.") in the v2.6.26 cycle.
