mips32: protect mips32r2 instructions with a flag

Regression issue that came when mips_dirtyhelper_calculate_FCSR was added.
Inline assembly with MIPS32r2 instructions needs to be protected by flags
that disable it for non-MIPS32r2 platforms such as some Broadcom boards.

Fixes the issue: Bugzilla 325124.
