kernel: backport 4.18 patch adding DMI_PRODUCT_SKU

Browse Source 
It's needed for applying some hardware quirks. This fixes:
drivers/net/wireless/broadcom/brcm80211/brcmfmac/dmi.c:60:20: error: 'DMI_PRODUCT_SKU' undeclared here (not in a function); did you mean 'DMI_PRODUCT_UUID'?
    DMI_EXACT_MATCH(DMI_PRODUCT_SKU, "T8"),

Fixes: 8888cb725d ("mac80211: brcm: backport remaining brcmfmac 5.2 patches")

Subject: [PATCH] firmware: dmi: Add access to the SKU ID string
This is used in some systems from user space for determining the identity
of the device.
Expose this as a file so that that user-space tools don't need to read
from /sys/firmware/dmi/tables/DMI
