writeprotect.h: add structure to represent chip wp configuration bits

Add `struct wp_bits` for representing values of all WP bits in a chip's
status/config register(s).

It allows most WP code to store and manipulate a chip's configuration
without knowing the exact layout of bits in the chip's status registers.

Supporting other chips may require additional fields to be added to the
structure.
