tests/qtest/npcm7xx_pwm-test: Only do full testing in slow mode

The npcm7xx_pwm-test can take quite a while when running with
--enable-debug on a loaded system. The tests here are quite
repetitive - by default it should be fine if we only execute
some of them and only execute all when running in slow testing mode.
