I've just pushed the fix for this to uefi-next and triggered a CI job.

To fix, I reverted part of this commit:

https://git.linaro.org/gitweb?p=arm/uefi/uefi-next.git;a=commit;h=9d59a88be171f74ae08ad63b3e8d1b77a87522e8
9d59a88 ArmPkg/ArmCpuLib: Fixed SMP Cortex-A9 and Cortex-A15

Specifically, the changes to file ArmPkg/Drivers/ArmCpuLib/ArmCortexA9Lib/ArmCortexA9Lib.c.

This is the same fix that also resolves the ATAGS version of this bug.

Tested. On ARM Versatile Express A9 board with Linaro Android image:

https://android-build.linaro.org/builds/~linaro-android/vexpress-linaro-mp/#build=274

Device Tree works well after UEFI upgraded:
