[PATCH v3] x86/cpuid: Rename hypervisor_cpuid_base() to cpuid_base_hypervisor()

["Ahmed S. Darwish" <darwi@linutronix.de>]

In order to let all the APIs under <cpuid/api.h> have a shared "cpuid_"
namespace, rename hypervisor_cpuid_base() to cpuid_base_hypervisor().

To align with the new style, also rename:

    for_each_possible_hypervisor_cpuid_base(function)

to:

    for_each_possible_cpuid_base_hypervisor(function)

Adjust call-sites accordingly.

 Changelog-v3: Fix commit subject line to include the new function name,
 cpuid_base_hypervisor().
