Andy Ross 453ce6afb8 samples/drivers/counter/alarm: Fix YAML schema failure
On my build host (where apparently the Python has a different version
of yaml than CI) this test is producing schema faiulres from the YAML:

    E: samples/drivers/counter/alarm/sample.yaml: can't load (skipping):
       <SchemaError: error code 2: Schema validation failed:
     - Value 'None' is not of type 'str'.
       Path: '/tests/test/harness_config/regex/1'.: Path: '/'>

The bug seems to be that the regex must be a list of strings, and the
empty list element is being parsed as a python None.  Just remove,
presumably the intent was an empty string, which is a noop in a regex
anyway.

Counter Alarm Sample
#####################

Overview
********
This sample provides an example of alarm application using counter API.
It sets an alarm with an initial delay of 2 seconds. At each alarm
expiry, a new alarm is configured with a delay multiplied by 2.

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

This sample requires the support of a timer IP compatible with alarm setting.
