kernel: add Qualcomm NSS dataplane ethernet driver

Qualcomm NSS-DP is as its name says Qualcomms ethernet driver for the NSS
subsystem (Networking subsystem) built-into various Qualcomm SoCs.

It has 2 modes of operation:
* Without NSS FW and rest of code required for offloading

This is the one that we will use as the amount of kernel patching required
for NSS offloading and the fact that its not upstreamable at all makes it
unusable for us.

Driver in this mode is rather basic, it currently only offers NAPI GRO
(Added by us as part of the fixup) and basically relies on the powerfull
CPU to get good throughput.

* With NSS FW and rest of code required for offloading

In this mode, driver just registers the interfaces and hooks them into
NSS-ECM to allow offloading.
This mode is not viable for use in OpenWrt due to reasons already described
above.

This driver is required for ipq807x to have wired networking until a better
one is available, so lets add the fixed-up version for 5.15 for now.

+Subject: [PATCH] switchdev: fix FDB roaming
+
+Try and solve the roaming issue by trying to replicate what NSS bridge
+module is doing, but by utilizing switchdev FDB notifiers instead of
+adding new notifiers to the bridge code.
+
+We register a new non-blocking switchdev notifier and simply wait for
+notification, and then process the SWITCHDEV_FDB_DEL_TO_DEVICE
+notifications.
+
+Those tell us that a certain FDB entry should be removed, then a VSI ID
+is fetched for the physical PPE port and using that VSI ID and the
+notification provided MAC adress existing FDB entry gets removed.

+
+The original method of connecting a PHY to the ethernet controller

+properties. This is redundant. The PHY node already contains the MDIO
+address, and attaching a PHY implies "link-poll".

+Utilize napi_gro_receive instead of plain netif_receive_skb on EDMA v1.
+
+Usually it provides quite a lot of RX speed improvements, however in some

+
+In cases where reduced performance is experienced its possible to disable
