this changed in the latest Brevitas export

Scaled and non-scaled QuantHardTanh activation tests separated. Non-scaled test includes cases with scale parameter == 1. In scaled test, bipolar activation is excluded as it's not currently supported

[Test] Change input argument to clock period for make_pynq_proj and create_stitched_ip  transformation

[Transformation and Test] Add option to adjust clock frequency in ipstitch and when making the pynq project get fclk from the metadata properties. Change tfc w1a1 test to test new feature

Add new test cases for QuantHardTanh. Cases for max > 1 and scaling_impl_type == ScalingImplType.PARAMETER with learned scale

thanks to @quetric for pointing this out
