Drop support for TEST_REPORTS

We always use the text report on the UART so drop the other report
formats (Junit) and destinations (file over semihosting). This
simplifies the report generation code.

 Then the test session begins. The TF-A tests are executed one after the
 other. Tests results are saved in non-volatile memory as we go along.
 
-Once all tests have completed, a report is generated. The TF-A tests currently
-supports 2 report formats:
-
--  Raw output, i.e. text messages over serial console.
-
--  Junit output, i.e. XML file generated over semihosting. This is useful when a
-   post-processing tool needs to parse the test report, as it is more
-   machine-friendly than the raw output.
-
-The report format to use is chosen at build time. For more information,
-refer to the section `Summary of build options`_ in the User Guide.
+Once all tests have completed, a report is printed over the serial console.

--  ``TEST_REPORTS``: List of desired test reports. Test reports are described by
-   a space-separated list of colon-separated pairs of report destination and
-   report type. Valid destinations are: 'uart' and 'semihosting'. Valid report
-   types are 'raw' (text output) or 'junit' (XML Junit format). The default is
