PS22, Line 56: struct wp_chip_config *cfg
Only realized this now: this requires the caller to know the size of
`struct wp_chip_config` which is currently not given by `libflashrom.h`.
IMO, we should use dynamic allocation instead, like in the rest of the
API. It will require yet another de-allocation function, but having a
clean, consistent API seems worth it.
