[U-Boot] [PATCH 1/4] x86: serial.dtsi: Add UART interrupt property

This patch adds the interrupt property for the legacy 0x3f8 NS16550 UART on standard 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.
