spi25_statusreg: inline spi_write_register_flag()
Creating the entire SPI command that should be sent to the chip in
spi_write_register() is simpler than splitting it across two functions
that have to pass multiple parameters between them.
Additionally, having separate spi_write_register_flag() function
provided little benefit, as it was only ever called from
spi_write_register().

to look at the new patch set (#49).

flashchips,writeprotect_ranges: add range decoding function
Allow chips to specify functions that map status register bits to
protection ranges. These are used to enumerate available ranges and
determine the protection state of chips. The patch also adds a range
decoding function for the example chips. Many other chips can also be
handled by it, though some will require different functions (e.g.
MX25L6406 and related chips).
Another approach that has been tried in cros flashrom is maintaining
tables of range data, but it quickly becomes error prone and hard to
validate.
Using a function to interpret the ranges allows compact encoding with
most chips and is flexible enough to allow chips with less predictable
ranges to be handled as well.

libflashrom,writeprotect: add functions for reading/writing WP configs
New functions are exposed through the libflashrom API for
reading/writing chip's WP settins: `flashrom_wp_{read,write}_cfg()`.
They read/write an opaque `struct flashrom_wp_cfg` instance, which
includes the flash protection range and status register protection mode.
This commit also adds `{read,write}_wp_bits()` helper functions that
read/write chip-specific WP configuration bits.

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.
