[ Upstream commit af4b3a6f36d6c2fc5fca026bccf45e0fdcabddd9 ]
The Predia Basic tablet contains quite generic names in the sys_vendor and product_name DMI strings, without this patch brcmfmac will try to load: brcmfmac43340-sdio.Insyde-CherryTrail.txt as nvram file which is a bit too generic.
Add a DMI quirk so that a unique and clearly identifiable nvram file name is used on the Predia Basic tablet.
