Oberon : SOL LED: Added module_params

Browse source 
Added module_param support to led-trig.ko module to set during 
init. This can be set to enable tri-led path in driver.

multi_led_enable = 0 : This is default setting only one led module will
be controlled.

multi_led_enable = 1 : Enable tri-led calls so individual brightness or
blink can be set for all (R,G,B) leds.
