video: tegra: host: Allow disabling debug dumps
cdma timeout produces a huge amount of debug data to UART. This is
usually useful, but in some cases this affects significantly to
timing.
This patch:
- adds ioctl for controlling whether the dump is required or not
- creates a debugfs node for forcing debug dump always
- moves job information dumping before changing the contents of
job data
