The naming standard at https://cwiki.apache.org/confluence/display/NUTTX/Naming+FAQ requires that all architecture-private functions begin with the name of the arch, not up_. This PR addresses only these name changes for the ARM-private functions up_instack_base() and up_instack_top() which should be called arm_instack_base() and arm_instack_top(). There should be no impact of this change (other that one step toward more consistent naming). Normal PR checks are sufficient

|
* setting up interrupt service routines, starting the clock, and
|
|
* registering device drivers are some of the things that are different
|
|
* for each processor and hardware platform.
|
|
*
|
|
* up_initialize is called after the OS initialized but before the user
|
|
* initialization logic has been started and before the libraries have
|
|
* been initialized. OS services and driver services are available.
