net: marvell: prestera: add firmware v4.0 support

Add firmware (FW) version 4.0 support for Marvell Prestera
driver. This FW ABI will be compatible with future Prestera
driver versions and features.

The previous FW support is dropped due to significant changes
in FW ABI, thus this version of Prestera driver will not be
compatible with previous FW versions.
