Add the following featute bits.
vnmi: Virtual NMI (VNMI) allows the hypervisor to inject the NMI into the
guest without using Event Injection mechanism meaning not required to
track the guest NMI and intercepting the IRET.
The presence of this feature is indicated via the CPUID function
0x8000000A_EDX[25].
automatic-ibrs :
The AMD Zen4 core supports a new feature called Automatic IBRS.
It is a "set-and-forget" feature that means that, unlike e.g.,
s/w-toggled SPEC_CTRL.IBRS, h/w manages its IBRS mitigation
resources automatically across CPL transitions.
The presence of this feature is indicated via the CPUID function
0x80000021_EAX[8].
The documention for the features are available in the links below.
