soc/amd/picasso: Drop _INI method and OperationRegion for AZHD device
_INI method for AZHD device for Picasso family was just copied from Stoneyridge as part of initial change. There is no evidence that this is required for Picasso. Also, removing the _INI method works perfectly fine. Thus, this change drops the _INI method for AZHD device on Picasso. Since the _INI method was the only entity using the OperationRegion fields, this change also drops the operation region.
