As of the gatesgarth you are no longer allowed to remove setscene tasks
as the eSDK generation expects for tasks to actually be executed.

Switch to use ?= to set KBRANCH_raspberrypi4-64 to make it easier to
override elsewhere when needed for switching to a different kernel branch.
Also make the same change for KMACHINE_raspberrypi4-64 to match how it is
assigned in the meta-yocto-bsp layer.

Although this dynamic layer currently only adds Xen support, it will
eventually hold other board and platform specific tweaks to core
meta-virt recipes.

Enable linux-yocto-dev as the Linux kernel for Xen on the
Raspberry Pi 4, with the bcm-2xxx-rpi4 KMACHINE and KBRANCH.
Set a Raspberry Pi SD card variable to increase the size of the boot
partition to accommodate both the kernel and the Xen hypervisor.

The GIC that is needed by Xen can be enabled via the rpi-config recipe
variable. Fixes the build after the upstream recipe changed recently.

Replaces the prior use of earlyprintk which is an x86-specific option.

Kernel patches are in process of Linux review and submission, and are
backported from the Linux Foundation's Eve Project kernel from 5.6 to 5.4
(some patches not needed for 5.4, hence gaps in the patch sequence number)
https://github.com/lf-edge/eve/tree/master/pkg/new-kernel/patches-5.6.x
A bbappend applies Xen overrides to the boot command line.
Since linux-raspberrypi depends on linux-yocto, and
linux-yocto_virtualization introduces a requirement for cfg/virtio.scc
obtain it from the yocto kernel cache.

A Xen-specific u-boot script is needed for launching Xen, and the GIC
(interrupt controller) needs to be enabled.
Since this is both Xen-specific and Raspberry Pi-specific, use a
dynamic layer to conditionally enable the recipes when both
meta-virtualization and meta-raspberrypi are in use together.
