media: imx: imx7_mipi_csis: Store CSI-2 data type in format structure

Browse Source 
Replace the register value stored in the csis_pix_format structure with
the CSI-2 data type. The register value is simply computed from the data
type using a shift. This prepares for i.MX8MP support that needs the
same data type in a different hardware register.
