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.

When processing command streams, make sure the host1x's stream ID is
programmed for the channel so that addresses are properly translated
through the SMMU.

The host1x hardware found on Tegra194 is mostly backwards compatible
with the version found on Tegra186, with the notable exceptions of the
increased number of syncpoints and mlocks. In addition, some rarely
used features such as syncpoint wait bases were dropped and some
registers had to move around to accomodate the increased number of
syncpoints.
