There are some cases where PN is not expanded into linux-yocto in the
arm-ffa-transport.inc file required from linux-yocto_%.bbappend,
because of the := usage, in those cases PN gets "defaultpkgname".
To fix the issue, rename "linux-yocto" folder into "files" and adjust
ARMFILESPATHS to point to that in linux-yocto_%.bbappend, prepend
ARMFILESPATHS to FILESEXTRAPATHS in arm-ffa-transport.inc.
Remove ARMFILESPATHS prepend from FILESEXTRAPATHS for corstone1000 in
meta-arm-bsp, because the platform has always the "arm-ffa" in
MACHINE_FEATURES, which causes ARMFILESPATHS to be prepended.
While there, remove the FILESEXTRAPATHS prepend of ARMFILESPATHS for
the n1sdp that will be added by arm-ffa-transport.inc only when
needed.

Arm generic timer provides different timers for different exception
levels and different secure states. Because Armv8-R AArch64 has secure
state only, the valid timer for hypervisor in EL2 is secure hypervisor
physical timer. But for platform fvp-baser-aemv8r64, before FVP 11.18,
the secure hypervisor physical timer could not work well in EL2, so we
had been using Non-secure physical timer in EL2 for hypervisor as a
workaround.
Since secure hypervisor physical timer issue has been fixed from FVP
11.18, we can use this correct timer in EL2 for hypervisor now. So we
update the device tree timer node to use secure hypervisor physical
timer interrupt for hypervisor.
About the interrupt assignments of FVP, please refer to
https://developer.arm.com/documentation/100964/latest/Base-Platform/Base---interrupt-assignments

The 64-bit fvp-base machine uses the upstream fvp-base-recv devicetree,
but fvp-base-arm32 was accidentally using the old
fvp-base-gicv3-psci-custom that we patch into the kernel.
As the only difference between these platforms at a "hardware" level is
whether the cores boot in 32- or 64-bit mode, they should both use
fvp-base-revc.
This isn't trivial as devicetree files need to be under the correct
arch/ directory, so we need to symlink into arch/arm the right files
from arch/arm64.
This has several improvements, but primarily virtio networking works so
we can now use testimage with fvp-base-arm32.
