media: ov5640: Remove redundant defines

The OV5640_SCLK2X_ROOT_DIVIDER_DEFAULT and OV5640_SCLK_ROOT_DIVIDER_DEFAULT
defines represent exactly the same setup, and are at the same value, than
the more consistent with the rest of the driver OV5640_SCLK2X_ROOT_DIV and
OV5640_SCLK_ROOT_DIV.

Remove them.
