arm: kirkwood: convert db-88f6281/db-88f6282 to the Device Tree This commit converts the Marvell DB-88F6281/DB-88F6282 board to the Device Tree. In fact, the code was supporting two different boards: one with the 6281 SoC variant, and one with the 6282 SoC variant. The difference between the two being that the 6281 has one PCIe interface, and the 6282 has two PCIe interfaces. In order to handle that with the Device Tree, we create a 'kirkwood-db.dtsi' file that contains the definitions common to both boards, and 'kirkwood-db-88f6281.dts' and 'kirkwood-db-88f6282.dts' for the definitions specific to each board. This is similar to what is done for the QNAP TS219 Kirkwood platform. We have kept one single Kconfig option, just like it was before.

ARM: kirkwood: Relocate PCIe device tree nodes Now that mbus has been added to the device tree, it's possible to move the PCIe nodes out of the ocp node, placing it directly below the mbus. This is a more accurate representation of the hardware. Moving the PCIe nodes, we now need to introduce an extra cell to encode the window target ID and attribute. Since this depends on the PCIe port, we split the ranges translation entries, to correspond to each MBus window. In addition, we encode the PCIe memory and I/O apertures in the MBus node, according to the MBus DT binding specification. The choice made is 0xe0000000-0xf0000000 for memory space, and 0xf200000-0xf2100000 for I/O space. These apertures can be changed in each per-board DT file.
