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.)
