[PATCH] OMAPDSS: DISPC: Use msleep instead of blocking mdelay

[Jassi Brar]

We have no reason to block in the error handler workqueue, so use msleep.

Thanks, applied.

As a side note, I hate that error handler =). It was a quick emergency

However, I don't really have a good idea what to do in case we get
errors from DSS HW.
