ichspi: Split ICH7 init out

The original, ICH7 init only shared about three lines with the newer,
ever growing ICH9+ init. That's not worth an indentation level in an
endlessly long function, so split it out.

We introduce a kind of "breakpoint" into the `ich_chipset' enum:

  SPI_ENGINE_ICH9

This marks all chipset entries below it as supporting this code path
and should help to avoid long `case' lists.

Tested read/erase/write on ThinkPad T60 (ICH7).
