mvebu: backport CN9130 dts necessary files changes to 5.4 1. Add support for Marvell CN9130 SoC 2. Add support for CP115,and create an armada-cp11x.dtsi file which will be used to instantiate both CP110 and CP115 3. Add support for AP807/AP807-quad,AP807 is a major component of CN9130 SoC series 4. Drop PCIe I/O ranges from CP11x file and externalize PCIe macros from CP11x file Signed-off-by: Ian Chang <ianchang@ieiworld.com> (cherry picked from commit c98ddf0f019986bbb4c868bfcaf97e0d1f4ee2dc) Signed-off-by: Daniel Golle <daniel@makrotopia.org>

Subject: [PATCH] arm64: dts: marvell: Drop PCIe I/O ranges from CP11x file
As an example, Armada 70x0 and 80x0 SoC 0xf9000000 region points to
RUNIT/SPICS0 while it is referenced in the DT as PCIe I/O memory
range. This shows that I/O memory has never been used/working on the
old SoCs despite the region being advertised. As PCIe I/O ranges will
not be supported in newer SoCs using CP11x co-processors, let's
simply drop them. It is not harmful in any case as PCIe device drivers
can do it all with the regular mapped memory anyway.
