All programmer access function prototypes except init have been made
static and moved to the respective file.

A few internal functions in flash chip drivers had chipaddr parameters
which are no longer needed.

The lines touched by flashctx changes have been adjusted to 80 columns
except in header files.

Struct flashchip is used only for the flashchips array and for
operations which do not access hardware, e.g. printing a list of
supported flash chips.

struct flashctx (flash context) contains all data available in
struct flashchip, but it also contains runtime information like
mapping addresses. struct flashctx is expected to grow additional
members over time, a prime candidate being programmer info.
struct flashctx contains all of struct flashchip with identical
member layout, but struct flashctx has additional members at the end.

The separation between struct flashchip/flashctx shrinks the memory
requirement of the big flashchips array and allows future extension
of flashctx without having to worry about bloat.

Push those changes forward where needed to prevent new sign
conversion warnings where possible.

See http://www.kernel.org/doc/Documentation/spi/spidev for an introduction.

Usage is as follows:

  flashrom -p linux_spi:dev=/dev/spidevX.Y

where X is the bus number, and Y device. It accepts an optional parameter
'speed' which allows to set the SPI clock speed in kHz.

Tested on an Atmel AVR32AP7000 board (NGW100 Network Gateway Kit), see
below, which was used to program a ThinkPad X60, but it should work on every
other Linux system, too.
