All currently available e3xx daugherboards are equivalent from
a UHD perspective, so make them consistently show up as "E3XX".

* Single class for loading firmware/FPGA images onto devices instead of multiple utilities
* Loading functions are registered for each device, corresponding to their --args="type=foo" name
* Deprecation warnings added to all product-specific image loading utilities
This was originally limited because it performed poor,
however, with refactoring that has been done since release,
this now gives better performance.

This commit will have UHD load the idle fpga image on
destruction of e300_impl.
Note: This requires usrp_e310_idle_fpga.bit to be present
in the UHD images directory.

- Logging in conjunction with B200 side-channel utility
(using UART or directly over USB)
- More and better configurability, e.g. Tx voltage swing
and DMA configuration
Fixes issue #828 "B200: Tx quadrature calibration regression in master"
Following commit added new gain table settings to reflect updated values
from ADI. Gain indices used by Tx Quad Cal were not matched to
accommodate the new tables.
2b06c38 "b2xx: dc offset and iq imbalance correction control"
Requirement for Tx Quad Cal is for TIA gain and analog LPF gain to be
set at 0 dB, or 0x20 in the gain table. Final effect is a dramatic
decrease in Tx DC offset and quadrature image.

Patch fixes a portion of #807
"B210: severe distortion on In-phase data for some gain settings"
ADI recommends that the "Prevent Pos Loop Gain" setting be enabled to
prevent the Rx quadrature tracking loop from becoming unstable at low
power levels. ADI Linux kernel driver also reflects this setting.
We do not follow the ADI recommendation. Adjust accordingly.

This patch resolves issue #823
"B200: Receive RF DC calibration makes calibration worse below 34 dB"
According to ADI reference documents, enabling any of the 3 LNA's in the
receive path causes a 180 degree phase shift. Correspondingly, we invert
the LNA bypass path (gain indices below 34 dB) to match. Testing,
however, reveals that one of these statements or the polarity inversion
setting itself is false. Disabling the switch results in expected
behavior and proper phase alignment.
Overall effect is up to 60 dB of DC offset suppression ahead of the Rx
analog LPF. This reduces the problematic dependency on active baseband
tracking and may resolves multiple tracking stability issues.
