Tegra4 host1x has an extra channel(totals 9), which caused bitfields in
a couple of registers to shift. The registers are mainly used in the
debug code to dump the channel FIFO. Same number of sync points as
Tegra3, but 12 wait bases.
Other changes are minor and driver already deals with them, for example
32-bit versus 16-bit sync point value comparison.
