T440P: Add Back Cover LED, Make it pulse like original

T440P has a red LED on the back as many of the newer thinkpads. coreboot did not support this.
The LED also remained on while the system was suspended unlike the stock firmware. Now this is fixed.

I usually turn it off except for suspend but I assume others will want the default behavior.
