In light of the commit 16f77de8 (Revert "MIPS: Save/restore MSA context around signals") the MSA support in the kernel is incomplete. Until the replacement for the former sigcontext changes is agreed upon and in tree, mark MSA experimental & disable it by default. MSA is only implemented by one CPU supported by the kernel, the P5600. The P5600 is a 32 bit core, and thus MSA can only be used when the experimental CONFIG_MIPS_O32_FP64_SUPPORT option is enabled. Therefore MSA is only being used in experimental settings anyway and this change doesn't actually make any difference beyond clarifying the state of MSA support.
