Subject: firmware: dmi_scan: Use lowercase letters for UUID
Git-commit: 712ff25450bd01366301eef81c33e865d901e7b7
Patch-mainline: v4.17
References: FATE#326044 bsc#1105835

RFC 4122 asks for letters a-f in UUID to be lowercase. Follow this
recommendation.

Suggested by Paul Dagnelie at:
https://savannah.nongnu.org/bugs/index.php?53569

Signed-off-by: Jean Delvare <jdelvare@suse.de>

Rationale for backporting this commit:
dmidecode in SLE15 SP1 has been updated to version 3.2 which contains
a smiliar change. We want dmidecode and the kernel to be consistent
in how they represent the system UUID.
