[coreboot] flashrom patch: make AT49F002N(T) chip work

Hello all,

This patch fixes support for the AT49F002N(T) chip in the flashrom tool.

It replaces the write function to one based on write_byte_program_jedec() 
instead of write_page_write_jedec(), as this part does not support page 
programming.
I have verified the NT variant to fully work now, and adjusted the test 
status accordingly. The N variant *should* also work with this patch, but 
remains untested.

Like my previous patch, this one is also based inside the flashrom 
directory.

Kind regards,
 	Tim.
