4.8-unstable: building firmware/hvmloader errors in Bookworm with gcc-12.2

[Pry Mar <pryorm09@xxxxxxxxx>]

Hello,

First attempt to build xen-4.18-unstabl in deb12 (Bookworm):

/home/mockbuild/pbdeps/xen-4.18~rc0/debian/build/build-utils_amd64/tools/firmware/hvmloader/dsdt_anycpu.asl   9851:             Name ( SLT, 0x0 )
Remark   2173 -          Creation of named objects within a method is highly inefficient, use globals or method local variables instead ^  (\_GPE._L03)

/home/mockbuild/pbdeps/xen-4.18~rc0/debian/build/build-utils_amd64/tools/firmware/hvmloader/dsdt_anycpu.asl   9852:             Name ( EVT, 0x0 )
Remark   2173 -          Creation of named objects within a method is highly inefficient, use globals or method local variables instead ^  (\_GPE._L03)
