	src/common/lib/libc/arch/mips/atomic: membar_ops.S

Log Message:
octeon: Add second errata syncw in membar_release

The second syncw is relevant to CN5xxx/Octeon+ for us (ERLite), we don't
currently support CN3xxx but attempt to clarify the commentary around all
this.

There is a seemingly similar detail on cnMIPS, the SYNC_PLUNGER, which is not
dealt with or changed here.  This syncw is specifically to work around two
related errata in CN3xxx and CN5xxx.

The OCTEON2 path is a future breadcrumb, we don't build it yet.
