platform/x86: int3472/discrete: Create a LED class device for the privacy LED
On some systems, e.g. the Lenovo ThinkPad X1 Yoga gen 7 and the ThinkPad
X1 Nano gen 2 there is no clock-enable pin, triggering the:
"No clk GPIO. The privacy LED won't work" warning and causing the privacy
LED to not work.
Fix this by modeling the privacy LED as a LED class device rather then
integrating it with the registered clock.
Note this relies on media subsys changes to actually turn the LED on/off
when the sensor's v4l2_subdev's s_stream() operand gets called.
