Upstream provides DTS(I) files for IPQ4019/AP-DK04.1, but we overwrite
them with local versions so far.
Remove the local files and use patches to be closer to upstream.
We already do the same for IPQ40xx/AP-DK01.1-C1.
Technically, this changes the compatible from "qcom,ipq4019" to
"qcom,ipq4019-dk04.1-c1", but it has never been implemented correctly
beforehand anyway.
