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.

+  - Initial revision
+
+There are 4 primary PowerPC ABIs.
+# *) Hard/Soft Floating Point
+# *) 32-bit/64-bit
+
+TUNE_ARCH is defined as either "powerpc" or "powerpc64" based on the m32 
+or m64 feature.
+
+May of the PowerPC package archictures are based on legacy Linux names.
+However, a general naming scheme should be similar to: ppc[64][<family>][-nf].
+(Note: the default package architectures are "powerpc" and "powerpc64".)
+
+TUNE_PKGARCH is defined as TUNE_PKGARCH_tune-${DEFAULTTUNE}.  All 
+PowerPC tunings are required to define TUNE_PKGARCH_tune-<tune>.
