serial: stm32: update conflicting RTS/CTS config comment
The comment for conflicting RTS/CTS config refers to "st, hw-flow-ctrl", but this property is deprecated since the generic RTS/CTS property has been introduced by the patch 'serial: stm32: Use generic DT binding for announcing RTS/CTS lines'. Update the comment to refer to both generic and deprecated RTS/CTS properties.
