Please split this patch into two patches.
1. A patch that updates arch/arm/boot/dts/r8a7791.dtsi
I suggest calling that patch
"ARM: shmobile: r8a7791: Add PCI device nodes"
2. A patch that updates arch/arm/boot/dts/r8a7791-koelsch.dts
I suggest calling that patch
"ARM: shmobile: koelsch: Add PCI device nodes"
