gpu: nvgpu: fix setup_rop_mapping for gm20b+

gm20b_init_gr does not inherit the ops set by gk20a_init_gr_ops, and the
gr.setup_rop_mapping HAL was not set there, so it was not set for chips
that inherit from gm20b_init_gr and do not override it explicitly.

Set the pointer in gm20b_init_gr, which other chips inherit, and delete
the surrounding if condition from the call, making sure that future
users always call it, because there is an implementation since the
earliest supported chip.
