LEDS: Update udev rule to pass $name than $devpath
Physical LED controller expects a sysfs path where it can find leds.
Current UDEV rule is passing $devpath and that works fine.
Because '-' is converted to '/' when systemd unit file processes it,
application needs to put a workaround to fetch the name of LED
correctly if the LED itself contains '-' in it.
Although $devpath still works to apply that workaround, it becomes
difficult for the workaround to look for a particular directory to
go beyond looking for led-name since not all LEDs would be having
/sys/devices/platform/leds/leds. However, all of those would share
'sys-class-leds' and hence passing 'sys-class-leds' with $name
makes it appropriate.
