[meta-freescale] [meta-fsl-arm PATCH v2 00/16] Machine overrides extender - reduce code duplication

[Otavio Salvador]

We spent some time trying to come up with something which would make
easier to extend the tune-arch support. All we could come up was way
too complex or did not work.

Instead We did a MACHINEOVERRIDES extender.

This enables the machine overrides extender for the i.MX6 devices. It
maps (spaces are used to easy the read):

  - mx6q  ->        imxipu imxvpu imxgpu2d imxgpu3d
  - mx6dl -> imxpxp imxipu imxvpu imxgpu2d imxgpu3d imxepdc
  - mx6sx -> imxpxp               imxgpu2d imxgpu3d
  - mx6sl -> imxpxp               imxgpu2d          imxepdc
  - mx6ul -> imxpxp
  - mx7d  -> imxpxp                                 imxepdc

So it allows for reusing of overrides while keeps this control at the
BSP side. For example, a PACKAGECONFIG setting which is common for
mx6q, mx6dl and mx6sx used to look as:

PACKAGECONFIG_mx6q  = "option"
PACKAGECONFIG_mx6dl = "option"

Now it can be replaced by:

PACKAGECONFIG_imxvpu = "option"

Changes in v2:
- Use BitBake event to insert the extends
- New patch.
