Muxes: Add symlink to /dev/i2c* support

It is difficult to tell what mux is what i2c channel
when looking at sysfs or d-bus alone. This creates
/dev/mux/<muxname>/<channelname> symlinks to aid other
applications.

Tested-by:

ls /dev/i2c-mux/Riser_*
/dev/mux/Riser_1_Mux:
PcieSlot1  PcieSlot2  PcieSlot3

/dev/i2c-mux/Riser_2_Mux:
PcieSlot1  PcieSlot2  PcieSlot3
