x86: crownbay: Add pci devices in the dts file
The Topcliff PCH has 4 UART devices integrated (Device 10, Funciton
1/2/3/4). Add the corresponding device nodes in the crownbay.dts per
Open Firmware PCI bus bindings.
Also a comment block is added for the 'stdout-path' property in the
chosen node, mentioning that by default the legacy superio serial
port (io addr 0x3f8) is still used on Crown Bay as the console port.
