"l2norm" => sums the square of the elements in vector X

Parameters

x_ptr	x vector input. 24bit integers unpacked.
out_ptr	output scalar. 32bit integer rounded by rounding_bits.
length	Number of elements in the vectors (data samples). Must be a multiple of 4, at least 8, and no greater than 1024.
rounding_bits	Number of bits to round the output by. 0 => no rounding, maximum of 31.

Returns

kAxonResultSuccess on success or a negative error code (see nrf_axon_result_e)
