gpu: host1x: Support 40-bit addressing
Tegra186 and later support 40 bits of address space. Additional registers need to be programmed to store the full 40 bits of push buffer addresses. Since command stream gathers can also reside in buffers in a 40-bit address space, a new variant of the GATHER opcode is also introduced. It takes two parameters: the first parameter contains the lower 32 bits of the address and the second parameter contains bits 32 to 39. Signed-off-by: Thierry Reding <treding@nvidia.com>
