Move hwaccess.h #include from flash.h to individual drivers.
libflashrom users need flash.h, but they do not care about hwaccess.h
and should not see its definitions because they may conflict with
other hardware access functions and #defines used by the libflashrom
user.

All programmer types (Parallel, SPI, Opaque) now register themselves
into a generic programmer list and probing is now programmer-centric
instead of chip-centric.
Registering multiple SPI/... masters at the same time is now possible
without any problems. Handling multiple flash chips is still unchanged,
but now we have the infrastructure to deal with "dual BIOS" and "one
flash behind southbridge and one flash behind EC" sanely.
A nice side effect is that this patch kills quite a few global variables
and improves the situation for libflashrom.
Hint for developers:
struct {spi,par,opaque}_programmer now have a void *data pointer to
store any additional programmer-specific data, e.g. hardware
configuration info.
Note:
flashrom -f -c FOO -r forced_read.bin
does not work anymore. We have to find an architecturally clean way to
solve this.

Remove the array spi_programmer, replace it by dynamic registration
instead. Also initially start with no busses supported, and switch to
the default non-SPI only for the internal programmer.
Also this patch changes the initialization for the buses_supported variable
from "everything-except-SPI" to "nothing". All programmers have to set the
bus type on their own, and this enables register_spi_programmer to just add
the SPI both for on-board SPI interfaces (where the internal programmer
already detected the other bus types), as well as for external programmers
(where we have the default "none").

SPI bitbanging on devices which speak SPI natively has a dual-use
problem: We need to shut down normal SPI operations to do the bitbanging
ourselves. Once we're done, it makes a lot of sense to reenable "normal"
SPI operations again. Add request_bus/release_bus functions to struct
bitbang_spi_master.
Add a bitbang shutdown function (not used yet).
Change MCP SPI and Intel NIC SPI to use the new request/release bus
infrastructure.
Cosmetic changes to a few error messages (80 column limit).
There are multiple possible strategies for bus request/release:
- Request at the start of a SPI command, release immediately afterwards.
- Request at the start of a SPI multicommand, release once all commands
of the multicommand are done.
- Request on programmer init, release on shutdown.
Each strategy has its own advantages. For now, we will stay with the
first strategy which worked fine so far.

- Fix incorrect whitespace, indentation, and coding style in some places.
- Drop '/**' Doxygen comments, we don't use Doxygen. Even if we would use
it, the comments are useless as we don't have any Doxygen markup in there.
- Use consistent vendor name spelling as per current website (NVIDIA,
abit, GIGABYTE).
- Use consistent / common format for "Suited for:" lines in board_enable.c.
- Add some missing 'void's in functions taking no arguments.
- Add missing fullstops in sentences, remove them from non-sentences (lists).
