Linux and QEMU SVSM branches updated

Hi,

As announced a couple of times I have now updated the Linux and QEMU branches
in our SVSM downstream forks to use the KVM planes patches based on Linux 7.1
and QEMU 11.0.0.

The new branches are at:

	Linux: https://github.com/coconut-svsm/linux/tree/svsm

	QEMU: https://github.com/coconut-svsm/qemu/tree/svsm

For QEMU the svsm-igvm branch works as well, both (svsm and svsm-igvm) point to
the same commit.

Everyone is urged to update their SVSM environment with the updated components
as they bring support for features the SVSM will start to rely on in future.

Please note the required change to the QEMU command line in order to get IRQs
routed correctly. The -machine parameter needs two properties:

	-machine q35,...,kernel-irqchip=split,device-plane=2

If you encounter any regressions please report them either on Github or here on
the mailing list.
