conf/machine/include: Cleanup PowerPC tunings to match README

Cleanup the PowerPC tunings to match the new tuning README file.

Default PowerPC to using TUNE_PKGARCH = ${TUNE_PKGARCH_tune-<tune>}

Fix AVAILTUNE settings in ppc603e, and ppce500mc to be addative.

Correct potentially overlapping "spe" definitions in ppce500 and ppce500v2.
