x86/cpuid: Use u32 in instead of uint32_t in <asm/cpuid/api.h>

Browse Source 
Use u32 instead of uint32_t in hypervisor_cpuid_base().

Yes, uint32_t is used in Xen code et al, but this is a core x86
architecture header and we should standardize on the type that
is being used overwhelmingly in related x86 architecture code.

The two types are the same so there should be no build warnings.
