media: ddbridge/mci: make ddb_mci_cmd() and ddb_mci_config() public
In preparation for splitting all MaxSX8 related code parts from the common MCI code, prefix both mci_cmd() and mci_config() functions with ddb_, remove the static marking and add matching function prototypes to ddbridge-mci.h so these functions can be reused from other files within the ddbridge driver. As this requires the mci-related structs to be defined in ddbridge-mci.h, move struct mci and struct mci_base there and clean them up. Picked up from the upstream dddvb GIT.
