Split off all code specific to the MaxSX8 cards to a separate ddbridge-sx8 module and hook it up in the Makefile. This also adds evaluation of the mci_type to allow for using different attach handling for different cards. As different cards can implement things differently (ie. support differing frontend_ops, and have different base structs being put ontop of the common mci_base struct), this introduces the mci_cfg struct which is initially used to hold a few specifics to the -sx8 submodule. While at it, the handling of the i/q mode is adjusted slightly. Besides this and handling mci_base and sx8_base struct pointers where needed, all code is copied unmodified from ddbridge-mci.c. Picked up from the upstream dddvb GIT. Signed-off-by: Daniel Scheller <d.scheller@gmx.net> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>
