The xenbus_probe patch to fix xen initialisation was mainlined in yocto-linux
v5.10.17. As oe-core has upgraded past this version, the patch can now be
dropped.

Adds a kernel patch to avoid Xen guest initialisation failure when converting a
virtual address to a frame number when the initial address space has a
non-contiguous physical layout.
The patch is mainlined for kernel versions >= 5.9, so we only apply it for
earlier versions.

The arm64-autonomy-guest kernel from commit 3499ba8198ca ("xen: Fix event
channel callback via INTX/GSI") are hanging at `xen🎈 Initialising
balloon driver`.
The arm-autonomy-guest kernels older than 5.10.17 need to backport the
0001-arm-xen-Don-t-probe-xenbus-as-part-of-an-early-initc.patch in order
to be able to boot.

The arm-autonomy-host kernels older than 5.10.13 need to backport the
0001-xen-Fix-XenStore-initialisation-for-XS_LOCAL.patch in order to be able to
use the `xl block-attach` and fix this issue:
```

libxl: error: libxl_xshelp.c:201:libxl__xs_read_mandatory: xenstore read failed: `/libxl/0/type': No such file or directory

This issue is not present in linux-linaro-arm[-rt] 5.4.0 used by N1SDP, hence
we do not apply this patch for it.
