Revert "flashchips: port S25FS(128S) chip from chromiumos"

This reverts commit a3519561bd0fb44153bb376322b799000657576f.

Breaks support for most SPI flash chips. It's too big and too
invasive to be reviewed as a single commit.

The changes to `spi_poll_wip():spi25.c` were not noticed in the
original review that were from the similarly named function and
file `s25f_poll_status():s25f.c` in the downstream Chromium fork.

V.2: Rebase and rephrase commit msg to reflect how the issue
     slipped in.
