n310: add capability to control RF filter bypass and freq.band limits

With the keywords "rx_gain_profile", "tx_gain_profile" and the new
values "default_bypass_always_off" and "default_bypass_always_on" the
customer can control whether the filter bypass shall be applied as
defined in the gain-table or whether to switch the bypass to ON or OFF
for all gains.

With the keywords "rx_band_map" and "tx_band_map" the user can define
custom frequency borders for the band mapping.

These new keywords can be used in the uhd.con, e.g.:
[type=n3xx]
rx_gain_profile=default_bypass_always_off
tx_gain_profile=default_bypass_always_on
rx_band_map=431e6;601e6;1051e6;1601e6;2101e6;2701e6
tx_band_map=723.18e6;1623.18e6;3323.18e6
