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"
