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().

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.

flash.h,flashchips.c: add writeprotect bit layout map to chips
This patch adds a register bit map `struct reg_bit_info`, with fields
for storing the register, bit index, and writability of each bit that
affects the chip's write protection. This allows writeprotect code to be
independent of the register layout of any specific chip. The new fields
have been filled out for example chips.
The representation is centered around describing how bits can be
accessed and modified, rather than the layout of registers. This is
generally easier to work with in code that needs to access specific bits
and typically requires specifying the locations of fewer bits overall.

spi25_statusreg: make register read/write functions generic
This patch adds new spi_{read,write}_register() functions that take the
source/destination register as an argument. Currently they can only
access SR1, support for other registers will be added in another patch.
Since we're refactoring things, this commit also makes
spi_read_register() return an error code, making it possible to identify
error conditions that spi_read_status_register() concealed.
This also removes the initial 100ms delay between writing a register and
the first attempt to check the chip's status. An initial delay was added
to avoid needing to read the status register multiple times, but that is
unlikely to cause problems on modern flash chips.
