4BA: Flashrom integration for the 4-bytes addressing extensions

This patch integrates code of the previous patch into Flashrom's code.
All the integrations is around 3 functions spi_nbyte_read, spi_nbyte_program
and spi_byte_program. After this patch then are not static and can be called
by their pointers saved in flashchips array. Also I added to flashrom.c some
code to switch a chip to 4-bytes addressing mode. And one error message is
corrected in spi.c because it's not suitable for 32-bit addresses.

Patched files

flash.h
+ added set of 4-bytes address functions to flashchip structure definition

flashrom.c
+ added switch to 4-bytes addressing more for chips which support it
