x86/CPU/AMD: Clear virtualized VMLOAD/VMSAVE on Zen4 client
commit a5ca1dc46a6b610dd4627d8b633d6c84f9724ef0 upstream.
A number of Zen4 client SoCs advertise the ability to use virtualized
VMLOAD/VMSAVE, but using these instructions is reported to be a cause
of a random host reboot.
These instructions aren't intended to be advertised on Zen4 client
so clear the capability.
