phy: remove unnecessary vendor extension fields

Browse Source 
When doing analogue beamforming, the beam ID for a pre-defined beam
table is passed directly to RU and there is no need to store the beam
table in PHY.

# FAPI implementation
To be noted that in our implementation analog beamforming is only supported in non-split/monolithic mode because we don't support yet SCF P19 interface that would be needed to manage these procedure in a split scenario with SCF FAPI.
To be noted that in our implementation analog beamforming is only partially supported in split mode.
The index based beamforming relies on the Tx precoding and beamforming PDU definition of beam-ID, where MSB is used to signal if the ID can be directly used or is it a pointer to a pre-stored vector of weights.
This definition of beam-ID is present only in the most recent versions of SCF PHY API specifications (at least from v8 and later, possibly from v6).
In `config_request` structure, a vendor extension (`nfapi_nr_analog_beamforming_ve_t`) configures the lower layers at initialization with the following information:
In addition to that, a `config_request` structure defined as vendor extension (`nfapi_nr_analog_beamforming_ve_t`) configures the lower layers at initialization with the following information:
- `analog_bf_vendor_ext` which can assume values 1 or 0 for enabling or disabling analog beamforming
- `num_beams_period_vendor_ext` which corresponds to the configuration parameter `beams_per_period`
- `total_num_beams_vendor_ext` which corresponds to the number of beams configured in `beam_weights`
- `analog_beam_list` which contains the RU beamforming indices configured in `beam_weights`
Additionally, L2 provides in each channel FAPI message information about the beam index. Small Cell Forum (SCF) FAPI provides in its PHY API specifications for the channels only a field for digital beamforming as part of the `precoding_and_beamforming` stucture. Therefore without a better option, we are currently using that one to store the internal analog beamforming index. This is the index used internally by the code to progressively identify the beam with a value from 0 to `total_num_beams_vendor_ext`.
Therefore, in case of analog beamforming, L2 provides in each channel FAPI message information about the beam index via the beam-ID parameter with MSB set to 1.
