Subject: [PATCH AUTOSEL 6.1 15/31] wifi: brcmfmac: Add DMI nvram filename quirk for ACEPC W5 Pro

From: Hans de Goede <hdegoede@...hat.com>

[ Upstream commit 32167707aa5e7ae4b160c18be79d85a7b4fdfcfb ]

The ACEPC W5 Pro HDMI stick contains 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 both too generic and messy with the $ symbols in the name.

The ACEPC W5 Pro uses the same Ampak AP6255 module as the ACEPC T8
and the nvram for the T8 is already in linux-firmware, so point the new
DMI nvram filename quirk to the T8 nvram file.
