[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.
