Document non-8-bits addressable memory support in NEWS

I think it would be a good idea to document that gdb now has (basic)
support to read/write memory on architectures with non-8-bits memory.
Hopefully somebody will see it and say "Hey!  We can now (more easily)
port GDB to our strange DSP that has 32-bits-addressable memory!" and do
it.

gdb/ChangeLog:

	* NEWS: Document support for non-8-bits addressable memory.
