[PATCH] firmware/dmi: Include product_sku info to modalias

[kaichuan . hsieh]

From: Kai-Chuan Hsieh <kaichuan.hsieh@xxxxxxxxxxxxx>

Some Dell platforms rely on modalias to customize configuration,
the product sku can be more specific for the hardware.

Add product_sku to modalias for better utilization.
