flash/nor, contrib/loaders: move numicro M0 write assembly to contrib/loaders

Browse Source 
Simply move numicro M0 flash write assembly to contrib/loaders. Also,
modify corresponding Makefile and generated numicro_m0.inc.

To make the path more general, this patch rename the path
"contrib/loaders/flash/numicro_m4" to "contrib/loaders/flash/numicro" as
well.
