[PATCH v1 3/5] baseband/acc: fix PF2VF Bug for FFT window probing

[Hernan Vargas]

Update of the PF2VF comms between bbdev and pf_bb_config to make sure
all FFT windows can be read.
So far only the first window was actually used and functional.
No system impact. Affects VRB1 and VRB2.

Fixes: 0d39ed91c161 ("baseband/acc: add FFT window width in VRB")
