Unify chip write functions

The currently used write functions (wrappers) all use helpers which
perform the actual write (inner functions).

The signature of the write wrappers is: int write_chip(struct flashchip
*flash, uint8_t * buf);

The signature of the inner write functions varied a lot. This patch
changes them to: int write_part(struct flashchip *flash, uint8_t *src,
int start, int len);

Did you know that flashrom has only 8 inner write functions for all
flash chips? write_page_write_jedec_common write_sector_jedec_common
write_sector_28sf040 spi_chip_write_256_new spi_chip_write_1_new
spi_aai_write_new write_page_82802ab write_page_m29f400bt

Export all inner write functions.

Change the function signature of wait_82802ab to eliminate single-use

Remove an error message in write_page_m29f400bt which was printed for
every byte written regardless of success.

Add sharplhf00l04.c to the list of flash chip drivers in the Makefile.
While the functions in there are unused, I suspect we will need them
later, and by hooking the file up we ensure that compilation won't
