Bug Description
[Impact]
Found on new platforms that UART require more than 1 second to respond
commands in the first 10 seconds after booted.
And the first command we send to scalar is dell_uart_
to tell if scalar is in charge of the backlight, and it always fails to get
response because of timeout.
[Fix]
Adding retry and increasing read timeout for dell_uart_
[Test]
Verified on the target Dell AIO, it can now read the response from scalar.
[Regression Potential]
Low, adding retry and increasing read timeout doesn't change the code flow.
