tools/x86/kcpuid: Update bitfields to x86-cpuid-db v2.0

Update kcpuid's CSV file to version v2.0, as generated by x86-cpuid-db.

Summary of the v2.0 changes:

* Introduce the leaves:

  - Leaf 0x00000003, Transmeta Processor serial number
  - Leaf 0x80860000, Transmeta max leaf number + CPU vendor ID
  - Leaf 0x80860001, Transmeta extended CPU information
  - Leaf 0x80860002, Transmeta Code Morphing Software (CMS) enumeration
  - Leaf 0x80860003 => 0x80860006, Transmeta CPU information string
  - Leaf 0x80860007, Transmeta "live" CPU information
  - Leaf 0xc0000000, Centaur/Zhaoxin's max leaf number
  - Leaf 0xc0000001, Centaur/Zhaoxin's extended CPU features

* Add a 0x prefix for leaves 0x0 to 0x9.  This maintains consistency with
  the rest of the CSV entries.

* Add the new bitfields:

  - Leaf 0x7: nmi_src, NMI-source reporting
  - Leaf 0x80000001: e_base_type and e_mmx (Transmeta)

* Update the section headers for leaves 0x80000000 and 0x80000005 to
  indicate that they are also valid for Transmeta.

Notes:
    Leaf 0x3, being not unique to Transmeta, is handled at the generated
    CSV file v2.3 update, later in this patch queue.

    Leaf 0x80000001 EDX:23 bit, e_mmx, is also available on AMD.  A bugfix
    is already merged at x86-cpuid-db's -tip for that, and it will be part
    of the project's upcoming v2.4 release.:
