The online help does not need a change.
But a man-page in the HTML documentation with an example showing
reassignment of stdios would be helpful.
In drv_system_init() we create a stdio device called "serial". Do we
need this dummy device if CONFIG_$(SPL_TPL_)DM_SERIAL=y? I find this
device duplicating the default serial device confusing.
