NOR FLASH: only erase/unlock whole sectors
Much to my surprise, I observed a "flash erase_address ..." command erasing data which I said should not be erased. The issue turns out to be generic NOR flash code which was silently, and rather dangerously, morphing partial-sector references into unrequested whole-sector ones. This patch removes that low-level morphing. If desired, it can and should be done in higher level code. (We might need to fix some stuff in the GDB server code.)
