Just did some reviews of the reserved-memory regions in other QCA devices and 
it looks like this tz and smem are often directly added to the SoC dtsi. So I 
will prepare a similar change for qcom-ipq4019.dtsi and this would then solve 
it for AP-DK01/04/07 and no changes in the board-family specific dtsi would be 
necessary.

But maybe someone has an objection because tz and smem can actually be 
disabled in a sane way on these SoCs and thus it would be better to have these 
regions in the board specific dts(i) files. We will see...

Kind regards,
