#90 Can't write flashes.

In case it doesn't support the multi byte write support, we will fail to write the flash.
I encountered this case with M29W320DB (AMD compatible).

I reviewed sources and it seems to be the similar bug in intel.c.

The single byte flashes I tested so far reported a 0 in this field.
Patch applied to amd.c and intel.c as r1459. Thanks for reporting.
