Transceiver52M: Add clipping detection on RACH input
Alert user of overdriven RACH input indicated by a positive
threshold detector result. This indication serves as notification
that the receive RF gain level is too high for the configured
transceiver setup.

umtrx: Don't use DSP tuning, because LMS6002D PLL steps are small enough.
We end up with DSP tuning just for 2-3Hz, which is meaningless and
only distort the signal.

UmTRX: Fix Tx gain setting procedure for the best signal quality.
We fixed setting Tx gain procedure in UHD, so we should fix it in osmo-trx too.
From our measurements, VGA1 must be 18dB plus-minus one and VGA2 is the best when 23dB or lower.

Transceiver52M: UHD: Exit on receive more than 100 timeout errors
Receiving timeout is not a fatal error and should be recoverable on network devices.
But for some reasons these errors are not always recoverable, in this case osmo-trx should be restarted.

UmTRX: Manually set Tx gain stages for the best signal quality.
New UHD versions support split configuration of Tx gain stages.
We utilize this to set the gain configuration, optimal for
the Tx signal quality. From our measurements, VGA1 must be
18dB plus-minus one and VGA2 is the best when 23dB or lower.
