cmsis_rtos_v1: support memory mapped stack at abort hook

Browse source 
This extends the thread abort hook to support memory mapped
stack. The calculation to find out to which instance of thread
pools the outgoing thread belongs requires physical address.
So find the physical address via the memory mapped stack for
that.
