From: "Dr. David Alan Gilbert" <linux@xxxxxxxxxxx>
pp_atomfwctrl_get_pp_assign_pin() and pp_atomfwctrl_get_pp_assign_pin()
were added in 2017 by
commit 0d2c7569e196 ("drm/amdgpu: add new atomfirmware based helpers for
powerplay")
but have remained unused.
Remove them, and the helper functions they used.
