x86/cpuid: Clean up <asm/cpuid/types.h>

 - We have 0x0d, 0x9 and 0x1d as literals for the CPUID_LEAF definitions,
   pick a single, consistent style of 0xZZ literals.

 - Likewise, harmonize the style of the 'struct cpuid_regs' list of
   registers with that of 'enum cpuid_regs_idx'. Because while computers
   don't care about unnecessary visual noise, humans do.
