powerpc: Define CPU feature for Architected 2.06 HV mode
This bit indicates that we are operating in hypervisor mode on a CPU compliant to architecture 2.06 or later (currently server only). We set it on POWER7 and have a boot-time CPU setup function that clears it if MSR:HV isn't set (booting under a hypervisor). Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
