Gregory Nutt 037c9ea0a4 arch/arm: Rename all up_*.h files to arm_*.h
Summary

The naming standard at https://cwiki.apache.org/confluence/display/NUTTX/Naming+FAQ requires that all MCU-private files begin with the name of the architecture, not up_.

This PR addresses only these name changes for the up_*.h files.  There are only three, but almost 1680 files that include them:

    up_arch.h
    up_internal.h
    up_vfork.h

The only change to the files is from including up_arch.h to arm_arch.h (for example).

The entire job required to be compatible with that Naming Convention will also require changing the naming of the up_() functions that are used only within arch/arm and board/arm.

Impact

There should be not impact of this change (other that one step toward more consistent naming).

* Clear a pending interrupt at the NVIC. This does not seem to be
* required for most interrupts. Don't know why...
*
* I keep it in a separate file so that it will not increase the footprint
* on Kinetis platforms that do not need this function.
