Nathan Chancellor 311607017e virt: Fix Kconfig warning when selecting TSM without VIRT_DRIVERS
After commit 3225f52cde ("PCI/TSM: Establish Secure Sessions and Link
Encryption"), there is a Kconfig warning when selecting CONFIG_TSM
without CONFIG_VIRT_DRIVERS:

  WARNING: unmet direct dependencies detected for TSM
    Depends on [n]: VIRT_DRIVERS [=n]
    Selected by [y]:
    - PCI_TSM [=y] && PCI [=y]

CONFIG_TSM is defined in drivers/virt/coco/Kconfig but this Kconfig is
only sourced when CONFIG_VIRT_DRIVERS is enabled. Since this symbol is
hidden with no dependencies, it should be available without a symbol
that just enables a menu.

Move the sourcing of drivers/virt/coco/Kconfig outside of
CONFIG_VIRT_DRIVERS and wrap the other source statements in
drivers/virt/coco/Kconfig with CONFIG_VIRT_DRIVERS to ensure users do
not get any additional prompts while ensuring CONFIG_TSM is always
available to select. This complements commit 110c155e8a ("drivers/virt:
Drop VIRT_DRIVERS build dependency"), which addressed the build issue
that this Kconfig warning was pointing out.

Say Y here to get to see options for device drivers that support
virtualization environments.
If you say N, all options in this submenu will be skipped and disabled.

help
Say Y here to use the hypervisor-provided Virtual Machine Generation ID
to reseed the RNG when the VM is cloned. This is highly recommended if
you intend to do any rollback / cloning / snapshotting of VMs.
Prefer Y to M so that this protection is activated very early.

help
The Freescale hypervisor management driver provides several services
to drivers and applications related to the Freescale hypervisor:
1) An ioctl interface for querying and managing partitions.
2) A file interface to reading incoming doorbells.
3) An interrupt handler for shutting down the partition upon
receiving the shutdown doorbell from a manager partition.
4) A kernel interface for receiving callbacks when a managed
partition shuts down.
