fix power estimation 

Some computation has been fixed in PUCCH reception.

SNR has been fixed, uses measurement instead of
a fixed value for the noise.

normalized_rx_power and target_rx_power have been removed,
replaced by snr and target_snr. All the files using those
variables have been updated.
