Move big PIO accesses from the interrupt handler to a workhandler
From: Hans Verkuil <hverkuil@xs4all.nl>
Sliced VBI transfers use PIO instead of DMA. 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.
