Does zama16b have some impact on zalasr

[romanheros]

From priviledged 1.13 specification, misaligned atomicity granule PMA has superseded the proposed Zam extension. I think we should explicitly remove the Zam description in Zalasr specificatio and add the Zama16b impact on it, as Zama16b has been selected as a develeopment optional extension in RVA23 profile.
