sandbox: Update PCI nodes in dts files The way the PCI nodes are written today causes a number of warnings if we stop disabling some of the warnings we pass to DTC. As these warnings aren't disabled in current Linux Kernel builds, we should aim to not disable them here either, so rewrite these slightly. Update the driver model doc as well.

pci: sandbox: Move the emulators into their own node Sandbox pci works using emulation drivers which are currently children of the pci device: pci-controller { pci@1f,0 { compatible = "pci-generic"; reg = <0xf800 0 0 0 0>; emul@1f,0 { compatible = "sandbox,swap-case"; }; }; }; In this case the emulation device is attached to pci device on address f800 (device 1f, function 0) and provides the swap-case functionality. However this is not ideal, since every device on a PCI bus has a child device. This is only really the case for sandbox, but we want to avoid special-case code for sandbox. Worse, child devices cannot be probed before their parents. This forces us to use 'find' rather than 'get' to obtain the emulator device. In fact the emulator devices are never probed. There is code in sandbox_pci_emul_post_probe() which tries to track when emulators are active, but at present this does not work. A better approach seems to be to add a separate node elsewhere in the device tree, an 'emulation parent'. This could be given a bogus address (such as -1) to hide the emulators away from the 'pci' command, but it seems better to keep it at the root node to avoid such hacks. Then we can use a phandle to point from the device to the correct emulator, and only on sandbox. The code to find an emulator does not interfere with normal pci operation. Add a new UCLASS_PCI_EMUL_PARENT uclass which allows finding an emulator given a bus, and finding a bus given an emulator. Update the existing device trees and the code for finding an emulator. This brings PCI emulators more into line with I2C.
