tests/pm_rps: vlv: wait for freq to settle

At least on VLV when forcing a new GT frequency by writing to the
min/max freq sysfs entries the kernel doesn't wait until the new
frequency settles, so the subsequent readback check might fail. To fix
this wait until the current frequency is between the min/max values
using a 10ms timeout.
