armv7m: implement async algorithm functions

Browse Source 
Split armv7m_run_algorithm into two pieces and use them to reimplement it.
The arch_info parameter is used to keep context between the two calls, so
both calls must refer to the same armv7m_algorithm struct. Ugly but works
for a proof-of-concept.
