Support specifying console options (like with console=ttyXN,<options>)
by appending them to the stdout-path property after a separating ':'.

Example:
        stdout-path = "uart0:115200";

This format breaks DT earlycon because libfdt doesn't recognize ':' as a
path terminator.

It's simple enough to fix this directly in early_init_dt_scan_chosen_serial()
but perhaps it would better to teach fdt_path_offset() to recognize ':'?

Hi Peter

ePAPR says for stdout-path in Chosen:

A string that specifies the full path to the node representing the
device to be used for boot console output. If the character ":" is
present in the value it terminates the path. The value may be an
alias.

So it is probably wise to implement this properly.
