x86/cpuid: Set <asm/cpuid/api.h> as the main CPUID header

The main CPUID header <asm/cpuid.h> was originally a storefront for the
headers:

    <asm/cpuid/api.h>
    <asm/cpuid/leaf_0x2_api.h>

Now that the latter CPUID(0x2) header has been merged into the former,
there is no practical difference between <asm/cpuid.h> and
<asm/cpuid/api.h>.

Migrate all users to the <asm/cpuid/api.h> header, in preparation of
the removal of <asm/cpuid.h>.

Don't remove <asm/cpuid.h> just yet, in case some new code in -next
started using it.
