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.
