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.
