johpow01 182ce10155 errata: workaround for Neoverse V1 errata 1940577
Neoverse V1 erratum 1940577 is a Cat B erratum, present in some
revisions of the V1 processor core.  The workaround is to insert a
DMB ST before acquire atomic instructions without release semantics.
This issue is present in revisions r0p0 - r1p1  but this workaround
only applies to revisions r1p0 - r1p1, there is no workaround for older
versions.
