Inspired by Linux commit c49a0a80137c7ca7d6ced4c812c9e07a949f6f24:
There have been reports of RDRAND issues after resuming from suspend on
some AMD family 15h and family 16h systems. This issue stems from a BIOS
not performing the proper steps during resume to ensure RDRAND continues
setup_clear_cpu_cap() is __init and hence may not be called post-boot.
Note that opt_pku nevertheless is not getting __initdata added - see
e.g. commit 43fa95ae6a ("mm: make opt_bootscrub non-init").

If one runs

default configuration value for the host's firmware kind, which is
"bios". If the configuration is then changed, things don't work.
This is confusing.
So ask the user to specify one or
Drop the explicit default from all the call sites. This centralises
the default. This is going to be the new scheme for host properties

(Two of the call sites had a different default, "", which in their
context was semantically equivalent to "bios".)

Currently, for a HVM on Xen, no reset method is virtualized. So in a VM's
perspective, assigned devices cannot be reset. But some devices rely on PCI
reset to recover from hardware hangs. When being assigned to a VM, those
devices cannot be reset and won't work any longer if a hardware hang
