This improves FullMAC firmware compatibility, adds logging in case of
firmware crash and *may* fix "Invalid packet id" errors.

+Subject: [PATCH] brcmfmac: Add DMI nvram filename quirk for ACEPC T8 and T11
+ mini PCs
+
+The ACEPC T8 and T11 mini PCs contain quite generic names in the sys_vendor
+and product_name DMI strings, without this patch brcmfmac will try to load:
+"brcmfmac43455-sdio.Default string-Default string.txt" as nvram file which
+is way too generic.
+
+The DMI strings on which we are matching are somewhat generic too, but
+"To be filled by O.E.M." is less common then "Default string" and the
+system-sku and bios-version strings are pretty unique. Beside the DMI
+strings we also check the wifi-module chip-id and revision. I'm confident
+that the combination of all this is unique.
+
+Both the T8 and T11 use the same wifi-module, this commit adds DMI
+quirks for both mini PCs pointing to brcmfmac43455-sdio.acepc-t8.txt .
