[media] dvb-frontends/cxd2841er: support CXD2837/38/43ER demods/Chip IDs

Those demods are programmed in the same way as the CXD2841ER/54ER and can
be handled by this driver. Support added in a way matching the existing
code, supported delivery systems are set according to what each demod
supports.

Updates the type string setting used for printing the "attaching..." log
line aswell.
