Look up xran_fh_init/xran_fh_config through driver instead of peaking into xran internals. Note that xran writes values back into these structs during initialization, and hence it is important to store them _after initialization_. Some remarks regarding less obvious changes: - slotnum is replaced by slots_in_sf: SLOTNUM_PER_SUBFRAME uses the time duration of a slot (=interval_us_local) to calculate the numbers of slots in a subframe, which can be done with a simple shift instead - The prach duration should be queried from the PRACH configuration table. The function to query the occasion info is part of the MAC layer code while this information can be used outside of this layer. Use header `nr_prach_config.h` to not duplicate functionality.
