Commit

    cbe37a4d2b3c ("ASoC: Intel: avs: Configure basefw on TGL-based platforms")

includes the main CPUID header from within a C function.  This works by
luck and forbids valid refactorings inside the CPUID header.

Include the CPUID header at file scope instead.

Note, for the CPUID(0x15) leaf number, use CPUID_LEAF_TSC instead of
defining a custom local macro for it.
