[PATCH v3 2/8] clk: imx6q: guard video clocks behind config

[Brian Ruley]

Do not touch the video clocks unless explicitly required by the
configuration. This avoids the issue of the binary size increase on SPL
builds that do not enable video. For those that do, they should increase
the size limit to fit the new code and data.
