Replaces the previous approach to define bands via hardware capabilities by the standard conforming concept of channel pages. In the short term this allows us to correctly calculate the PHY specific symbol rate and several parameters that directly depend from the symbol rate and were previously not being correctly calculated for some of the drivers whose channel pages could not be represented previously: * We now support sub-nanosecond precision symbol rates for UWB. Rounding errors are being minimized by switching from a divide-then-multiply approach to a multiply-then-divide approach. * UWB HRP: symbol rate depends on channel page specific preamble symbol rate which again requires the pulse repetition value to be known * Several MAC timings are being corrected based on the now correctly calculated symbol rates, namely aTurnaroundTime, aUnitBackoffPeriod, aBaseSuperframeDuration. In the long term, this change unlocks such highly promising functional areas as UWB ranging and SUN-PHY channel hopping in the SubG area (plus of course any other PHY specific feature).
