Subject: [PATCH] media: mtk-vcodec: Always signal source change event on format change

Currently the driver signals the source change event only in case of
a midstream resolution change, however the initial format detection
is also defined as a source change by the V4L2 codec API specification.
Fix this by signaling the event after the initial header is parsed as
well.
