At present sandbox sets non-blocking I/O as soon as any input is read
from the terminal. However it does not restore the previous state on
exit. Fix this and drop the old os_read_no_block() function.
This means that we always enable blocking I/O in sandbox (if input is a
terminal) whereas previously it would only happen on the first call to
tstc() or getc(). However, the difference is likely not important.

At present sandbox assumes that device-tree control is active, but this
may not be the case in SPL or TPL. Add some conditions to handle this.

In raw mode, handle ctrl-c as normal. This allows normal ctrl-c behavior
such as aborting a command that is timing out without completely
terminating the sandbox executable.
In [1], Simon disabled this. His reason for it was that it interferes
with piping test scripts. Piping should be done in cooked mode, so this
change should still not interfere.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.

At present devices use a simple integer offset to record the device tree
node associated with the device. In preparation for supporting a live
device tree, which uses a node pointer instead, refactor existing code to
access this field through an inline function.

Now that driver model support is available, convert sandbox over to use it.

The current sandbox serial driver is a pretty trivial example and does not
have the featues that might be needed for other board serial drivers. To
help provide a better example, add a text colour property to the device
tree for sandbox. This uses platform data, a device tree node, driver
private data and a remove() method.

It is useful for Cltl-C to be handled by U-Boot as it is on other boards.
But it is also useful to be able to terminate U-Boot with Ctrl-C.
Add an option to enable signals while in raw mode, and make this the
default. Add an option to leave the terminal cooked, which is useful for
redirecting output.

Add a simple LCD driver which uses SDL to display the image. We update the
image regularly, while still providing for reasonable performance.
Adjust the common lcd code to support sandbox.
For command-line runs we do not want the LCD to be displayed, so add a
--show_lcd option to enable it.

Implements the tstc() interface for the serial driver. Multiplexing
the console between the serial port and a keyboard uses a polling
method of checking if characters are available; this means that the
serial console must be non-blocking when attempting to read
characters.

Implement support for CONFIG_SERIAL_MULTI into sandbox serial driver.
This driver was so far only usable directly, but this patch also adds
support for the multi method. This allows using more than one serial
driver alongside the sandbox driver. Also, add a weak implementation
of default_serial_console() returning this driver.
