gpu: nvgpu: Implement gp10b variant of cbc_ctrl

Pascal has support for more comptags than Maxwell, but we were using
gm20b definitions for cbc_ctrl on all chips. Specifically field
clear_upper_bound is one bit wider in Pascal.

Implement gp10b version of cbc_ctrl and take that into use in Pascal
and Volta.
