video: tegra: Improve hdmi worker
original change by Mike J. Chen <mjchen@google.com>, but some changes
were made to bring it onto the newer kernel.
- fixed checkpatch warnings.
- used rt_mutex instead of spinlocks, as irq handler is threaded.
original commit message below:
It's now a full blown state machine. Ported from similar work
we did for OMAP. Handles TV's that occassionally drop HPD
briefly.
This also fixes a deadlock that could happen because the
old worker function grabbed the dc->lock, but then later
calls a function that grabs the fb lock. FB_BLANK ioctl
grabs the same locks but in the oppossite order. The
new worker thread does not grab the dc->lock.
