SDR receiver has ADC (Analog-to-Digital Converter) and SDR transmitter
has DAC (Digital-to-Analog Converter). Originally I though it could
be good idea to have own type for receiver and transmitter, but now I
feel one common type for SDR is enough. So lets rename it.

[hans.verkuil@cisco.com: this was added in 4.4, so update 4.2 to 4.4]
