drivers: video: introduction of the stm32 DCMIPP driver

The STM32 Digital Camera Memory Interface Pixel Processor (DCMIPP)
is a multi-pipeline camera interface allowing to capture
and process frames from parallel or CSI interfaces depending on its
version.
Current commit introduces the support of the 3 pipes version with
CSI input.
