Bob Paauwe 4cc40ad4fe igt/test/pm_rps: load GPU to force not-idle to idle transition.
When changing the sysfs GT min frequency, the kernel won't
automatcilly drop the GT frequency to idle unless the GPU
transitions from busy to idle.

Load the GPU after increasing the GT min frequency to force
a busy to idle transition. This matches the behavior when
decreasing the GT min frequency.
