drm/bridge/sii902x: Add missing dependency on I2C_MUX

Browse Source 
kbuild test robot reports:

>> ERROR: "i2c_mux_add_adapter" [drivers/gpu/drm/bridge/sii902x.ko] undefined!

Quite obviously the driver depends on I2C_MUX, but adding a "depends on"
introduces a recursive dependency, therefore this patch selects I2C_MUX
instead.
