ucm2: Add setting LED Mode in SetLED macro

Browse source 
Add 'Mode' argument to SetLED macro in order to allow setting a
different LED mode. This will allow mute switches with inverted
values to control the LEDs with 'follow-route' option instead of
default 'follow-mute'.

The Mode argument is optional.
