Disable NVM support by default
Change the default value of the USE_NVM build flag to 0.
The idea behind storing test results in NVM was that it makes it
possible to retrieve them post-mortem if some TFTF test crashes badly
or hangs the board and you have to power it off. But we never got to
develop the tooling that enables this use case.
Also, when NVM support is enabled, it allows to resume an interrupted
test session wherever you left it. At least that's the theory but in
practice it seems to have cause more issues than it has helped.
Until we make it easy to use the features enabled by USE_NVM=1, we
might as well disable NVM support, as this significantly slows tests
down.
