Merge remote-tracking branch 'origin/remove_power_reduction_for_MIMO' into integration_2024_w42 (!3004)

This hotfix removes division by num_antenna_ports in PDSCH precoding matrix generation.
These matrices are defined for CSI reporting in this way but here we are using them for
transmission and this results in an unwanted 10*log10(num_antenna_ports) reduction in
transmit power (3dB for 2 antenna ports, 6dB for 4 antenna ports, etc.)
