AM33xx/AM43xx Soc has 6 UART interfaces. Any of these 6 UARTs can be used as
serial console as defined by the specific board design and passing a proper
console bootarg. Given this, we should be able to use any UART(that is
used as serial console) for low level debugging. Currently only UART1 can
be used for low level debugging. So, adding support for all other UARTs
instead of waiting for new board with a different UART console.

Well we should just switch over to the standard 8250 debug code
instead. With multiarch the port detection for debug_ll port is
no longer needed. And we can still keep the Kconfig options for
various ports.
