Add support for Atmel AT26DF041
Wicked chip: No WRSR, no write enable command (but swallows our default one without a problem), supports an auto-erasing page write (but even without that page writes are recommended to write the whole page i.e. operate on a completely erased page), mad requirements on block refreshments if only partly written. Found on my Intel D946GZIS and tested with my serprog in situ. Using the page write by setting JEDEC_BYTE_PROGRAM to 0x11 and using the spi_chip_write_256 command greatly improves performance and works flawlessly. Corresponding to flashrom svn r1616.
