media: vivid: fix timestamp and sequence wrapping
The error injection controls that test wrap-around sequence and timestamp counters were partially broken. Add a menu option for 64 or 32 bit signed timestamp wrapping. Prevent the timestamp from wrapping around before the device can be tested. Remove the sequence count from the timestamp calculation so that sequence wrapping does not interfere with the timestamp. Add consistent time and sequence wrapping to sdr and touch devices.

media: vivid: fix (partially) timing issues
The vivid driver is a bit flaky w.r.t. the kthread timing, esp. when running inside a virtual machine.
This is caused by calling schedule_timeout_uninterruptible(1) which can actually take more than one jiffie. A while loop with schedule() turns out to be a lot more precise. Also, if mutex_trylock() fails, then just call schedule() instead of schedule_timeout_uninterruptible(1). There is no need to wait until the next jiffer, just schedule(), then try to get the lock again.
This is still not precise enough, it is still relatively easy to get missed frames. This really should be converted to use a proper timer, but for now this solves the worst problems.

media: split test drivers from platform directory
When the first test device was added (vivi.c), there were just one file. I was too lazy on that time to create a separate directory just for it, so I kept it together with platform.
Now, we have vivid, vicodec, vim2m and vimc. Also, a new virtual driver has been prepared to support DVB API.
So, it is time to solve this mess, by placing test stuff on a separate directory.
It should be noticed that we also have some skeleton drivers (for V4L and for DVB). For now, we'll keep them separate, as they're not really test drivers, but instead, just examples. The DVB frontend ones will likely be part of a new DVB test driver. By that time, it should make sense to move them here as well.

media: vivid: Add touch support
Support to emulate touch devices in vivid driver. It generates touch patterns simulating single tap, double tap, triple tap, move from left to right, zoom in, zoom out, palm press simulating large area being pressed on screen, and simulating 16 different simultaneous touch points.The values generated are based on behavior of the rmi_f54 driver.
