Enable generic earlycon support for nios2. This e.g. allows to use a 8250/16650 UART as earlycon. In order to get the earlycon, we just need to call parse_early_param() in early_init_devtree() as soon as the device tree is initially scanned. By adding an stdout-path property to the dts (done in this patch for 10m50_devboard), the earlycon can be used. In order to provide early printk support, we need to provide a dummy implementation of early_console_write(), so that arch/nios2/kernel/early_printk.c can still be compiled if neither SERIAL_ALTERA_JTAGUART_CONSOLE nor SERIAL_ALTERA_UART_CONSOLE is selected. As soon as the altera_uart and altera_jtaguart support earlycon, the entire file can be removed.
