[FHI72] Handle long PRACH format

Browse Source 
Only static long PRACH configuration verified, i.e. PRACH C-plane
is ignored by the RU.

Note: Introducing `N_ZC` and `num_prbu` parameters is needed for testing
with xran F release. However, in the K release, this information is
stored in xran_rx_packet_ctl struct.

In addition, PRACH format 0 is also verified with FW v2.0.5. An example gNB config file can be found at [`gnb.sa.band77.273prb.fhi72.2x2-benetel550-long-prach.conf`](../targets/PROJECTS/GENERIC-NR-5GC/CONF/gnb.sa.band77.273prb.fhi72.2x2-benetel550-long-prach.conf). On the RU side, the following parameters shall be modified:
```bash
mimo_mode=1_3
prach_format=long
prach_freq_offset_dynamic=false
lf_prach_compression_enable=true
lf_prach_slot_id=0
```
