This - in conjunction with the previous changes - makes it possible to use the STV0367 DVB-C/T demodulator driver with Digital Devices hardware having this demodulator soldered on them (namely CineCTv6 bridges and some earlier DuoFlex CT addon modules). The changes do the following: - add a third *_attach function which will make use of a third frontend_ops struct which announces both -C and -T support (the same as with DD's own driver stv0367dd). This is necessary to support both delivery systems on one FE without having to do large conversions to VB2 or the need to select either -C or -T mode via modparams and the like. Additionally, the frontend_ops point to new "glue" functions which will then call into the existing functionality depending on the active delivery system/demod state (all used functionality works almost OOTB). - Demod initialisation has been ported from stv0367dd. DD's driver always does a full init of both OFDM and QAM cores, with some additional things. The active delivery system is remembered and upon switch, the Demod will be reconfigured to work in OFDM or QAM mode (that's what the ddb_setup_XX functions are used for). Note that in QAM mode, the DD demods work with an IC speed of 58Mhz. It's not very good to perform full reinits upon Demod mode changes since in very rare occasions this can lead to the I2C interface or the whole Demod to crash, requiring a powercycle, thus the flag to perform full reinit is set to disabled. - A little enum is added for named identifiers of the current Demod state. Initialisation code/register writes originate from stv0367dd. Permission to reuse was formally granted by Ralph Metzler <rjkm@metzlerbros.de>.
