Hello build bot (Jenkins), Nico Huber, Edward O'Callaghan, Angel Pons, Anastasia Klimchuk, Sergii Dmytruk,

to look at the new patch set (#23).

Change subject: libflashrom,writeprotect: add flashrom_wp_{read,write}_chip_config()
......................................................................

libflashrom,writeprotect: add flashrom_wp_{read,write}_chip_config()

The read/write functions map between register values and `struct
wp_chip_state` using the chip's register bit map.

All currently supported chips can be handled with a single pair of
read/write functions, though an option for chips to override them might
be necessary in the future.
