video: tegra: host: Enhance FIFO/GATHER debug_dump
Enhance nvhost_debug_dump() output, as follows:
- Swap FIFO and GATHER dump so that even if GATHER dump blows out
seq_printf 1k buffer, we still have FIFO information;
- Write FIFO signature pattern (0xd???d???) to indirect save input
data to help pinpoint FIFO position within debug dumps;
- Prevent long data sequences from blowing out the seq_printf 1k
buffer, by limiting such sequences to 64 words.
