media: fe_property_parameters.rst: better document bandwidth

Use a table to document the supported bandwidths. That makes
it clearer to readers.

-  #. On DVB-C and DVB-S/S2, the bandwidth depends on the symbol rate.
-     So, the Kernel will silently ignore setting :ref:`DTV-BANDWIDTH-HZ`.

-  #. For DVB-C and DVB-S/S2, the Kernel will return an estimation of the
-     bandwidth, calculated from :ref:`DTV-SYMBOL-RATE` and from
-     the rolloff, with is fixed for DVB-C and DVB-S.

-  #. For DVB-S2, the bandwidth estimation will use :ref:`DTV-ROLLOFF`.

-  #. For ISDB-Tsb, it can vary depending on the number of connected
