x86: crownbay: Support Topcliff integrated pci uart devices with driver model

Browse Source 
In order to make a pci uart device node to be properly bound to its
driver, we need make sure its parent node has a compatible string
which matches a driver that scans all of its child device nodes in
the device tree.

Change all pci bridge nodes under root pci node to use "pci-bridge"
compatible driver, as well as corresponding <reg> properties to
indicate its devfn. At last, adding "u-boot,dm-pre-reloc" to each
of these nodes for driver model to initialize them before relocation.
