libflashrom,writeprotect: add support for reading/writing WP configs

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.
