The latest kernel with TDX support should be pulled from a different
repo (https://github.com/intel/linux-kernel-dcp, instead of
https://github.com/intel/tdx), and the latest version to be used is
SPR-BKC-PC-v9.6.
With the new version being used, let's make sure we enable the
INTEL_TDX_ATTESTATION config option, and all the dependencies needed to
do so.

Passing the URL to be used to download the kernel tarball is useful in
various scenarios, mainly when doing a downstream build, thus let's add
this new option.
This new option also works around a known issue of the Dockerfile used
to build the kernel not having `yq` installed.

There's no need to have the entire function for building SEV / TDX

Let's remove those functions and create a `get_tee_kernel()` which takes

Replaces calls of nproc with nproc with
nproc ${CI:+--ignore 1}
to run nproc with one less processing unit than the maximum to prevent
DOS-ing the local machine.
If process is being run in a container (determined via whether $CI is
null), all processing units avaliable will be used.

The apply_patches.sh script applies all patches in the patches
directory, as well as subdirectories. This means if there is a sub-dir
called "experimental" under a major kernel version directory,
experimental patches would be applied to the default kernel supported by
Kata.
We did not come accross this issue earlier as typically the experimental
kernel version was different from the default kernel.
With both the default kernel and the arm-experimental kernel having the
same major kernel version (5.15.x) at this time, trying to update the
kernel patch version revealed that arm-experimental patches were being
applied to the default kernel.
Restricting the patches to be applied to the top level directory will
solve the issue. The apply_patches script should ignore any
sub-directories meant for experimental patches.

Provide the `/proc/config.gz` file in guest kernels that allow the guest
to determine the kernel configuration used to build the running kernel.
Note that since `gunzip` expects to rename the gzip'ed file it operates
on, to use this feature you need to run something like the following in
the container environment:
```bash
# cat /proc/config.gz|gunzip -c
```

Pull #2795 recently added support for a closer-to-OCI behaviour for
VFIO devices, in which they appear to the container as VFIO devices,
rather than being interpreted by the guest kernel. However, in order
to use this, the Kata guest kernel needs to include the VFIO PCI
driver, along with dependencies like the Intel IOMMU driver.
The kernel as built by the scripts within Kata don't currently include
those, so this patch adds them.

The guest kernel configuration suggested for Kata, and which is used by the
CI didn't include CONFIG_PCI_MMCONFIG. That's kind of weird, MMCONFIG is
the modern normal way of handling configuration cycles.
In addition, due to a complex set of interactions through the ACPI code,
disabling MMCONFIG means that SHPC hotplug doesn't work: the driver is
included in the guest kernel, but will fail to probe on PCI to PCI bridges,
meaning it won't actually be activated.
Enable MMCONFIG so that we suggest and testa more typical guest kernel
configuration.

Optional build types are common for early adoption.

After 5.11-rc4, memory hotplug alignment size is reduced to 128M for 4K
page.
It works better for memory hotplug and nvdimm plug in kata on arm.
without this patch, memory hotplug will fail for the current memory
hotplug alignment is 1G but the nvdimm size align with 128M in kata.
After port it here, we can avoid a fix in qemu side.
Note: if you change the page size to other size than 4K, memory hotplug
will has no effect.
