mfd: si476x-cmd: Update si476x_cmd_am_rsq_status()'s kerneldoc

4 of the old arguments were grouped and moved into a struct which
is now passed as a pointer instead of the arguments themselves.
However, whoever carried out this work forgot to update the
function's kerneldoc header.

Fixes the following W=1 warnings:
