[PATCH 4/8] platform/x86: int3472: Add tps68470-led as clock consumer

[Daniel Scally <dan.scally@ideasonboard.com>]

Some of the LEDs provided by the TPS68470 require the clock that it
provides to be active in order to function. Add the platform driver
for the leds as a consumer of the clock so that the led driver can
discover it during .probe()
