* the inc file was dropped in:
58f5ac6 kernel: drop 5.10 .inc
but this .bbappend still causes parsing error, because 5.10 recipes
were removed from oe-core

The default preferred Linux kernel for Xen on the Raspberry Pi 4 is
linux-yocto. The alternative provided option is linux-yocto-dev, but
this is unintentionally a branch tracking configuration rather than a
fixed revision.
Remove the linux-yocto-dev in favour of the linux-yocto kernel version
5.15 which has been tested and verified working on the board.

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.

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.

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.
