nucleo_l496zg: samples: console/echo: It doesn't echo

[gon1332]

Describe the bug
The echo sample doesn't seem to work as expected.
The motivation to try this sample, was after I wrote a sample using tty.h and it could not receive data through tty_read(). My sample is a driver for a camera module. I've also mocked the camera behaviour via FTDI but nothing this function doesn't seem to response. I've also tried different UART ports.

To Reproduce
Steps to reproduce the behavior:

1. west build -b nucleo_l496zg -s samples/subsys/console/echo
2. west flash
3. Type anything
4. See unexpected behaviour

Expected behavior
It should echo back the input.

Screenshots or console output
In the output below, you can also see this artifact. It happens every time when the sample starts.

***** Booting Zephyr OS v1.14.0-rc1-669-g9ec9c430b312 *****
You should see another line with instructions below. If not,
the (interrupt-driven) console device doesn't work as expected:
Start typing characters to see them echoed back
�I speak to the void, but it doesn't echo back to me..

Environment (please complete the following information):

• OS: Linux with minicom
• Toolchain: Zephyr SDK
• Commit hash: 9ec9c43

If that's actual console-shot, then it actually shows characters echoed back ;-).

Otherwise, as the sample suggest, there's an issue with interrupt-driven UART functions implementation.

Can you try other BOARD's, starting with qemu_x86 ?

Damn, you're right. Sorry for that one.
