media: rcar-vin: Fix stride setting for RAW8 formats

Commit Message

Earlier versions of the datasheet where unclear about the stride setting
for RAW8 capture formats. Later datasheets clarifies that the stride
only process in this mode for non-image data. For image data the full
stride shall be used. Compare section "RAW: 8 Bits and Embedded 8-Bit
Non-Image Data, User Defined 8-bit Data" vs "RAW: 8 Bits".

Remove the special case from pixel formats that carry image data and
treat it as any other image format.
