device: Introduce pcidev_on_root() and friends
Semantics of dev_find_slot() are ill in the sense that
it only works after device enumeration has completed in
ramstage. Plan is to declare it as deprecated.
Introduce pcidev_on_root() and pcidev_path_on_root()
functions to replace cases where this was called with
static argument bus == 0. New implementation only walks
the root bus of the PCI tree, while old one walked
the entire linked list of devices.
Introduce pcidev_path_behind() to replace cases where
argument bus != 0. The required parent node is typically
one of the PCIe root functions that you locate using
pcidev_on_root() above.
New forms are safe to use with early devicetree and
before PCI bus numbers have been assigned.
