[PATCH v2] media: camss: vfe: Don't call hw_version() before its dependencies are met

[Robert Foss]

vfe->ops->hw_version(vfe) is being called before vfe->base has been
assigned, and before the hardware has been powered up.

Fixes: b10b5334528a9 ("media: camss: vfe: Don't read hardware version needlessly")
