media: bcm2835-unicam: Clear clock state when stopping streaming

raspberrypi inclusion
category: feature
bugzilla: 50432

--------------------------------

Commit 65e08c465020d4c5b51afb452efc2246d80fd66f failed to clear the
clock state when the device stopped streaming. Fix this, as it might
again cause the same problems when doing an unprepare.
