Nordic Semiconductor Radio peripheral provides IQ samples as
12 bits signed integer with sign extended to 16 bits.
Where out of range IQ samples (saturated) have value -32768.
Due to conversion of IQ samples to 8 bit signed integer, required by
BT 5.3 Core Vol 4, Part E sections 7.7.65.21 and 7.7.65.22 the
saturation information was lost.
The PR fixes that issue by use of value -128 to mark saturated
IQ samples. Note that BT 5.3 Core does not give any particular
value of IQ sample a special meaning.
This is a vendor specific solution and does not affect other
implementations of lower link layer.
