intel-microcode: Add ability to filter microcode
The microcode data file released by Intel has microcode for many Intel processors, which by default all get installed onto the target image. In some situations it may desirable to choose microcode for only a selected processor or processors. This change provides an easier way to filter and select only the microcode of interest for BSPs from recipe space. A new variable, UCODE_FILTER_PARAMETERS, is introduced, which can be defined to contain parameters to the iucode_tool which will filter the microcode of interest for the BSP under consideration. More information on the iucode-tool parameters is available here: http://manned.org/iucode-tool. This filtering makes the generated microcode files very machine-specific, hence making the recipe machine-specific. BSPs using the common Intel kernel will not be using the filtered microcode, and will be able to share the intel-microcode packages with the common Intel package arch for the recipe.
