Workaround for Cortex N1 erratum 1946160
Cortex N1 erratum 1946160 is a Cat B erratum present in r0p0, r1p0, r2p0, r3p0, r3p1, r4p0, and r4p1. The workaround is to insert a DMB ST before acquire atomic instructions without release semantics. This issue is present starting from r0p0 but this workaround applies to revisions r3p0, r3p1, r4p0, and r4p1, for previous revisions there is no workaround.
