Subject: mlxsw: reg: Add fields to PMAOS register
Patch-mainline: v5.16-rc1
Git-commit: ef23841bb94ab525363e9161847894df70ee49ad
References: jsc#PED-1549
The Ports Module Administrative and Operational Status (PMAOS) register
configures and retrieves the per-module status. Extend it with fields
required to support various module settings such as reset and power
mode.
