[ Upstream commit a8e5a110c0c38e08e5dd66356cd1156e91cf88e1 ]
The Acer A1 840 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-BayTrail.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 Acer A1 840 tablet.
