The UniPhier serial driver has been converted to driver model.
Let's remove uniphier_serial_initialize() call from the old
serial driver framework.

The stdio_dev structure has a private pointer for its creator, but it is
not set up by the serial system. Set it to point to the serial device so
that it can be found by code called by stdio.

For sandbox we have a fallback console which is used very early in
U-Boot, before serial drivers are available. Rather than try to guess
when to switch to the real console, add a flag so we can be sure. This
makes sure that sandbox can always output a panic() message, for example,
and avoids silent failure (which is very annoying in sandbox).

At present stdio device functions do not get any clue as to which stdio
device is being acted on. Some implementations go to great lengths to work
around this, such as defining a whole separate set of functions for each
possible device.
For driver model we need to associate a stdio_dev with a device. It doesn't
seem possible to continue with this work-around approach.
Instead, add a stdio_dev pointer to each of the stdio member functions.
Note: The serial drivers have the same problem, but it is not strictly
necessary to fix that to get driver model running. Also, if we convert
serial over to driver model the problem will go away.
Code size increases by 244 bytes for Thumb2 and 428 for PowerPC.

gd->bd->bi_baudrate is a copy of gd->baudrate.
Since baudrate is a common feature for all architectures,
keep gd->baudrate only.
It is true that bi_baudrate was passed to the kernel in that structure
but it was a long time ago.

U-Boot contains a lot of duplicit implementations of serial_puts()
call which just pipes single characters into the port in loop. Implement
function that does this behavior into common code, so others can make
easy use of it.
This function is called default_serial_puts() and it's sole purpose
is to call putc() in loop on the whole string passed to it.

If case the get_current() call fails before relocation, the U-Boot
must try to print an error message, fail and either reset or halt.
Such error is critical enough to halt the system, as it means the
system is in very bad state.
This is now also used in SPL, since CONFIG_SERIAL_MULTI is enabled
unconditionally. To avoid compiling whole vsprintf.c into SPL, use
puts() to print error message and hang() to stop the system in case
of SPL build.
