drm/amdgpu: drop ih reroute function from psp v11

Browse source 
For all the ASICs that integrate psp v11, vega20
doesn't support ih reroute. arcturus and later will
allow kernel driver to program ih_cfg_index/data
through mmio directly. navi1x and onwards will only
support grb_ih_set command in sriov configuration.

psp_v11_0_reroute_ih is not needed any more.
