This patch adds the interrupt property for the PCI HS-UART NS16550 UART on Bay Trail x86 platforms. This can be used to enable the RX interrupt buffer support of the ns16550 driver, so that even very long lines can be pasted in the U-Boot console shell.
Please note that in general the interrupt number should be read from the PCI config registers by the UART driver. But since the UART driver is called very early in the init process, these PCI config registers are not initialized yet at this time. And since the PCI interrupt configuration is also fixed in the dfi-bt700.dtsi file, adding this one interrupt property to the UART DT node will not cause any problems with dynamic interrupt assignments resulting in a different interrupt number for this PCI device.
