[meta-freescale] [meta-fsl-arm][PATCH] libimxvpuapi: Add new recipe

[Carlos Rafael Giani]

A few notes:

* Even though COMPATIBLE_MACHINE is set to (mx6), the packages are still 
in the cortexa9hf-vfp-neon folder, not in the 
tmp/deploy/ipk/cortexa9hf-vfp-neon-mx6qdl. Not sure if this is OK. The 
library's API contains no bits and #includes that are machine specific 
in any way.

* I noticed that libfslvpuwrap recipe sets PACKAGE_ARCH = 
"${MACHINE_ARCH}" . I am wondering if this would make sense for the 
libimvpuapi one as well. It does depend on imx-vpu, which contains 
machine specific bits in its headers (like, "#if defined(IMX6Q)"). Or is 
there a different reason why the libfslvpuwrap recipe sets the 
PACKAGE_ARCH to MACHINE_ARCH?

* The libfslvpuwrap recipe use COMPATIBLE_MACHINE = "(mx6q|mx6dl)" 
instead of COMPATIBLE_MACHINE = "(mx6)" . I am not aware of the entire 
mx6 production line. Are there imx6 machines without a VPU? If so, does 
"(mx6q|mx6dl)" include all machines that *do* have a VPU?
