Kumar Gala 21cf3a6344 samples: Fix filtering on UART_CONSOLE
There were a few different issues with the UART_CONSOLE filtering:
* Filter was incorrect - UART_CONSOLE should be CONFIG_UART_CONSOLE
* platform_exclude was used for drivers that had a #error for lack of
  interrupt support.  We can now use CONFIG_SERIAL_SUPPORT_INTERRUPT in
  the filter for that.  This catches all the various drivers that needed
  don't support uart interrupts, not just the onces that had a #error

console_getline() Sample Application
####################################

Overview
********

This example shows how to use :cpp:func:`console_getline()` function.
Similar to the well-known ANSI C gets() and fgets() functions,
:cpp:func:`console_getline()` either returns the next available input
line or blocks waiting for one. Using this function, it should be fairly
easy to port existing ANSI C, POSIX, or Linux applications which process
console input line by line. The sample also allows to see details of how
a line is returned by the function.

If you are interested in character by character console input, see
:ref:`console_getchar_sample`.


Requirements
************

UART console is required to run this simple.


Building and Running
********************

The easiest way to run this sample is using QEMU:

.. code-block:: console

   $ cd samples/console/getline
   $ make BOARD=qemu_x86
   $ make BOARD=qemu_x86 run

Now start pressing keys on a keyboard, followed by Enter. The input line
will be printed back, with a hex code of the last character, to show that
line does not include any special "end of line" characters (like LF, CR,
etc.)
