<asm/processor.h> includes the CPUID API header <asm/cpuid/api.h>, but
all what it actually needs are data types from <asm/cpuid/types.h>.

Modify the header to include <asm/cpuid/types.h> instead.

Note, this allows the CPUID API header to include <asm/processor.h> next,
without inducing a circular dependency.  This will be needed by the
upcoming centralized CPUID model APIs.

Note, a large number of call sites were already using the CPUID APIs
without including <asm/cpuid/api.h>.  They directly or indirectly
included <asm/processor.h>, which included the CPUID API header.  Such
call sites have been modified, by parent commits, to explicitly include
the CPUID API header instead.
