[PATCH] serial: 8250_early: Add earlycon support for Synopsys DesignWare ABP UART
Some board like Hisilicon D02 uses Synopsys DesignWare ABP UART, declare an OF early console for it, so early console device can be enabled with comand line "earlycon"(without option) via the "stdout-path" property in device-tree.
