UART on Quark platfor, according to Quark BSP Programmer's
Reference Manual, is located in the following order on PCI bus:
COM2 BAR0: 16550 registers
BAR1: DMA registers
COM1 BAR0: 16550 registers
BAR1: DMA registers
So, the driver on Quark platform has to specify BAR (Base
Address Registers) number, the pci_bus_scan() function looks for.
As long as UART is a concole device, calling pci_show() during
it's initialization does not make any output.
