ipa: rpi: Add a HW property to determine if the data buffer is strided
This property (dataBufferStrided) indicates if the CSI-2 hardware writes
to the embedded/metadata buffer directly, or if it treats the buffer
like an image buffer and strides the metadata lines.
Unicam writes this buffer strided, while the PiSP Frontend writes to it
directly. This information will be relevant to data parsers in the
helpers where the data is structured in lines.
