[U-Boot] [PATCH v3] spi: Add error checking for invalid bus widths

[Simon Glass]

At present an invalid bus width prints a message but does not return an
error. This is the opposite of the correct behaviour. Adjust it to avoid
code bloat in the common case, and avoid hard-to-debug failure in the
uncommon case.

Changes in v3:
- Display an error in U-Boot proper, but then continue
- Drop patches previously applied
