[PATCH] pc-bios/canyonlands.dts: Fix some DeviceTree warnings

[Philippe Mathieu-Daudé]

canyonlands.dts was imported in 2018, in commit 4b387f9ee1
("ppc: Add aCube Sam460ex board"). The file content is based
on Linux file arch/powerpc/boot/dts/canyonlands.dts from
commit 5edc2aae16bc. Then Linux added 2 commits on top:
- 86bc917d2ac1 ("powerpc/boot/dts: Fix dtc "pciex" warnings")
- eca213152a36 ("powerpc/4xx: Complete removal of MSI support")

Backport the same commits in order to fix some of the following
warnings which started to appear since commit 6e0dc9d2a8 ("meson:
compile bundled device trees"):
