radioInterface: Operate on real Tx power attenuation rather than on device specific gains

All the Tx gain related APIs are left out of reach from radioInterface,
and in there we simply interact with radioDevice passing the attenuation
received from TRXC.

Prior gain logic is moved in base radiodevice class, with the idea that
the setTxGain() and related functions will be dropped over time in each
sublcass in favour of an specific implementation of the
SetPowerAttenuation API.
