Now that qualcommax exists as a target and dependencies have been updated
let move ipq807x support to subtarget of qualcommax.
This is mostly copy/paste with the exception of having to update SSDK and
NSS-DP to use CONFIG_TARGET_SUBTARGET.
This is a preparation for later addition of IPQ60xx and IPQ50xx support.

Currently, ipq807x only covers Qualcomm IPQ807x SoC-s.
However, Qualcomm also has IPQ60xx and IPQ50xx SoC-s under the AX WiSoC-s
and they share a lot of stuff with IPQ807x, especially IPQ60xx so to avoid
duplicating kernel patches and everything lets make a common target with
per SoC subtargets.
Start doing that by renaming ipq807x to qualcommax so that dependencies
on ipq807x target can be updated.

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.
