These patches try to enhance the support of the various delays by adding
into the core the necessary logic to derive the actual symbol duration
(and then the lifs/sifs durations) depending on the protocol used. The
symbol duration type is also updated to fit smaller numbers.

Having the symbol durations properly set is a mandatory step in order to
use the scanning feature that will soon be introduced.

Changes since v2:
* Added the ca8210 driver fix.
* Fully dropped my rework of the way channels are advertised by device
  drivers. Adapted instead the main existing helper to derive durations
  based on the page/channel couple.
