WORKAROUND: Revert "staging: bcm2835-codec: Format changed should trigger drain"

This reverts commit b7e6b495eff31298ba4665f71b2414cc9a8f99c2.

When setting last buffer done on format changed event, bcm2835-codec does not
work for decoding because it recognizes there is no queued buffer even it is
not well fit for v4l2 codec spec. Maybe it is because v4l2 codec gst plugin
v4l2 usage is not up to date in tizen. Until properly fixing it, revert it
to support video h/w decoding on rpi4 in tizen.
