Fix support for USRP UHD Versions => 4.5.0.0
UHD versions above 4.5 changed some variable names and were braking the TDD patch application when compiled from sources. This merge creates a new patch with the new variable names and applies in case the UHD version is 4.5.0.0, 4.6.0.0 or 4.7.0.0 while leaving previous behavior untouched.
