This is slightly slower (ha, ha), but works on boards with a locked
opmenu. Tested on ICH7 and works.

At some point the flash bus will be part of struct flashchip.

Pardon me for pushing this in, but I think it is important to beware of further
decay and it will improve things for other developers in the short run.

Carl-Daniel, I will consider your suggestions in another patch. I want to keep
things from getting too much for now. The patch includes Rudolf's VIA SPI
changes though.

It is similar with few documented exceptions to ICH7 SPI controller.

r3393 assumed that ICH7 always used SPI. This patch resets ich7_detected back
to 0 when BOOT BIOS Straps indicate something else than SPI.

Also fixes a build error in ichspi.c with gcc 4.2.2.

* ICH7 SPI support
* fix some variable names in ichspi.c (Offset -> offset)
* Dump ICH7 SPI bar with -V
* Improve error message in case IOPL goes wrong. (It might not even be an IOPL)

This is done by using the generic SPI interface.
