[U-Boot] [PATCH v1 03/14] colibri-imx6ull: set module variant depending on config block

From: Stefan Agner <stefan.agner at toradex.com>

Using CPU temperature grading as a discriminator if the Wi-Fi /
Bluetooth chip is populated is no longer possible due to upcoming
SKUs. Set variant to -wifi only if a valid config block is present
and the product id mentions a SKU with Wi-Fi / Bluetooth.
