The problem is centred around the way the driver keeps _two_ cached copies of the current settings - one of the struct video_picture settings, and one of the registers. When the decoder is re-initailised, the cached register settings are overwritten, as are the values in the hardware registers. However, the cached video_picture settings are not. Resolve this by removing the useless and buggy second level of caching for video_picture. Instead, provide a function which updates register values if and only if the value we are going to write to the register has changed.

This was done inside the interrupt handler, but since PIO accesses are very slow this meant that a lot of time was spent inside the interrupt handler. All PIO copies are now moved to a workqueue. This should fix various issues with missing time ticks and remote key hits.
