Robert Hoo 465932db25 x86/cpu: Add new VMX feature, Tertiary VM-Execution control 
A new 64-bit control field "tertiary processor-based VM-execution
controls", is defined [1]. It's controlled by bit 17 of the primary
processor-based VM-execution controls.

Different from its brother VM-execution fields, this tertiary VM-
execution controls field is 64 bit. So it occupies 2 vmx_feature_leafs,
TERTIARY_CTLS_LOW and TERTIARY_CTLS_HIGH.

Its companion VMX capability reporting MSR,MSR_IA32_VMX_PROCBASED_CTLS3
(0x492), is also semantically different from its brothers, whose 64 bits
consist of all allow-1, rather than 32-bit allow-0 and 32-bit allow-1 [1][2].
Therefore, its init_vmx_capabilities() is a little different from others.
