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.
