[PATCH] tests/qtest/npcm7xx_pwm-test: Be less verbose unless V=2

[Peter Maydell]

The npcm7xx_pwm-test produces a lot of output at V=1, which
means that on our CI tests the log files exceed the gitlab
500KB limit. Suppress the messages about exactly what is
being tested unless at V=2 and above.

This follows the pattern we use with qom-test.
