Merge branch 'qcom-dts-updates'

Alex Elder says:

====================
arm64: dts: qcom: DTS updates

This series updates some IPA-related DT nodes.

Newer versions of IPA do not require an interconnect between IPA
and SoC internal memory.  The first patch updates the DT binding
to reflect this.

The second patch adds IPA information to "sc7280.dtsi", using only
two interconnects.  It includes the definition of the reserved
memory area used to hold IPA firmware.

The last patch defines the reserved IPA firmware memory area in
"sc7180.dtsi".
