The structs phy_rx_agc_info and phy_status_rpt define parts of the
header data that the r8188eu chipset sends to this driver via usb.
Add a comment to clarify that we cannot modify the content of these
structures and remove seemingly unused fields.

Dear all,
I experimented with "cleaning up" these structures and related code before
discovering that their content comes from usb packets we receive from the
r8188eu chipset.
Would it make sense to add a word of warning to prevent others from
repeating this exercise?
Thanks,
Martin
