DM355 CCDC hw module
Adds ccdc hw module for DM355 CCDC. This registers with the bridge
driver a set of hw_ops for configuring the CCDC for a specific
decoder device connected to vpfe.

+ * CCDC hardware module for DM355
+ * --
+ *
+ * This module is for configuring DM355 CCD controller of VPFE to capture
+ * Raw yuv or Bayer RGB data from a decoder. CCDC has several modules
+ * such as Defect Pixel Correction, Color Space Conversion etc to
+ * pre-process the Bayer RGB data, before writing it to SDRAM. This
+ * module also allows application to configure individual
+ * module parameters through VPFE_CMD_S_CCDC_RAW_PARAMS IOCTL.
+ * To do so, application include dm355_ccdc.h and vpfe_capture.h header
+ * files. The setparams() API is called by vpfe_capture driver
+ * to configure module parameters
+ *
+ * TODO: 1) Raw bayer parameter settings and bayer capture
+ * 2) Split module parameter structure to module specific ioctl structs
+ * 3) add support for lense shading correction
+ * 4) investigate if enum used for user space type definition
+ * to be replaced by #defines or integer
