The dcache flushing code path was conditional on ARM && !DCACHE config
options. However, dcaches exist on other platforms as well and may need
clearing if their driver requires it.
Simplify the compile logic and always enable the dcache flush logic in
the video core. That way, drivers can always rely on it to call the arch
specific callbacks.
This will increase code size for non-ARM platforms with CONFIG_VIDEO=y
slightly.
