apalis/colibri_t30: add more console uart configurations
Add more UART configurations to the device trees allowing easy
switching of the console UART port by changing the UART base address
of the console node within the device tree e.g. for using UART2 on
Apalis T30 as follows:
console = "/serial@70006300";
To use it for Linux as well one needs to modify the debug_uartport
kernel boot argument e.g. for using UART2 on Apalis T30 as follows:
setenv setup 'setenv setupargs gpt gpt_sector=${gptoffset} igb_mac=
${ethaddr} no_console_suspend=1 console=tty1 console=ttyS0,${baudrate}n
8 debug_uartport=lsport,3 ${memargs} fbcon=map:1'
