x86: additional defconfig updates

Additional updates to the x86 defconfigs.  The goals are, as before:

- Make them usable to testers, more so than distributors or end users,
  both of which are likely to have their own config already.
- Keep 32 and 64 bits as similar as is practical.

Changes:

- Use a more generic CPU type (ppro and generic, respectively).
- Bump number of CPUs to 64 (few if any NR_CPUS arrays left).
- Enable PAT.
- Enable OPTIMIZE_INLINE.
- Enable microcode update support.
- Build SMT scheduler support (in addition to MC).
