head -r365677 and later do not have the xhci related DMA problem fixed

[Mark Millard]

I finally got around to updating the systems that I have access
to, including the 8 GiByte RPi4B, from head -r363590 to -r363932 .
This puts the sytem after then head -r365677 check in of the
attempted DMA fix that involved restricting the xhci DMA range to
1 GiByte.

I've tested head -r363932 under uefi/ACPI v1.20 with the
3072 limit disabled and it failed the large file duplicate
and diff/cmp test:

# cp -aRx /usr/obj/clang-armv7-on-aarch64.tar /usr/obj/clang-armv7-on-aarch64.alt_tar
# diff /usr/obj/clang-armv7-on-aarch64.tar /usr/obj/clang-armv7-on-aarch64.alt_tar
Binary files /usr/obj/clang-armv7-on-aarch64.tar and /usr/obj/clang-armv7-on-aarch64.alt_tar differ
# cmp -l /usr/obj/clang-armv7-on-aarch64.tar /usr/obj/clang-armv7-on-aarch64.alt_tar | head -30

For reference:

# ls -ldT /usr/obj/clang-armv7-on-aarch64*
-rw-r--r--  1 root  wheel  11570948096 Jul 18 18:32:37 2020 /usr/obj/clang-armv7-on-aarch64.alt_tar
-rw-r--r--  1 root  wheel  11570948096 Jul 18 18:32:37 2020 /usr/obj/clang-armv7-on-aarch64.tar

(So the over 10 GiByte original file is significantly larger than the
8 GiByte RAM.)
