SNP initialization is forced during PSP driver probe purely because SNP can't be initialized if VMs are running. But the only in-tree user of SEV/SNP functionality is KVM, and KVM depends on PSP driver for the same. Forcing SEV/SNP initialization because a hypervisor could be running legacy non-confidential VMs make no sense. This patch removes SEV/SNP initialization from the PSP driver probe time and moves the requirement to initialize SEV/SNP functionality to KVM if it wants to use SEV/SNP.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
