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.
BUG=b:155132752
TEST=Verified that audio still works on Trembyle
