DRC events can happen virtually at anytime, including when we are
starting a seek. Should this happen, we must make sure to return to the
DRC state, otherwise the firmware will expect buffers of the new
resolution whereas userspace will still work with the old one.
Returning to the DRC state upon resume for seeking makes sure that the
client will get the DRC event and will reallocate the buffers to fit the
firmware's expectations.

Oops, please ignore as this seems to depend on another patch... I will
repost once I can figure out the correct dependency chain, unless
Stanimir can find a better way to handle DRC during seek and flush.

This patch depends on [1] series which is still under review.
