[OE-core] [PATCH 0/2] Simplify tune-cortexa*.inc, and add cortex-a5 tuning

[Andy Voltz]

This series puts the common tuning setup in an include and reworks the
tuning files for each cortex-a* series to use that include. A new variable,
CORTEX_ID is used to specify which processor is used.

Add a tuning file for the cortex-a5 using this include.

This was tested on a vybrid twr_vf600 build which uses cortex-a5.
