fix: dvb was missing I2C_MUX support and si2168 driver

These are required due to how the PCIe tuner is actually wired.

Components on the card:
- Silicon Labs Si2157 (tuners, 4)
- Silicon Labs Si2168 B40 (demodulators, 4)
- Conexant CX23888 (PCIe Interfaces, 2)
- Pericom PI7C9X2G304 (PCIe switch, 1)
