[meta-freescale] [meta-fsl-arm][PATCH 08/33] imx-base: Add mx7 support to U-Boot, MACHINE filter and DEFAULT_TUNE

[Lauren Post]

This is the tune feature we tested with for mx7.  I can investigate changing it going forward but it will not align to what was tested in this release (and in the upcoming beta for 7d).  I prefer to change it once we have a test cycle with the change.

Is there a reason to disallow thumb?
the t in "cortexa9thf-neon" has recently be added.
