CONFIG_WATCHDOG_AUTOSTART option which cause that watchdog is not
automatically started by U-Boot during init phase, like when CONFIG_WDT
option is not set at all.

[mtd: cfi_flash: Fix CFI flash driver for 8-bit bus support] finally
fixed this 8-bit bus support. But also broke some other boards using
this cfi driver. So this patch had to be reverted.

I spotted a different, simpler approach for this 8-bit bus support
on the barebox mailing list posted by
Oleksij Rempel <bug-track@fisher-privat.net>:

http://www.spinics.net/lists/u-boot-v2/msg14687.html

Here the commit text:

"
Many cfi chips support 16 and 8 bit modes. Most important
difference is use of so called "Q15/A-1" pin. In 16bit mode this
pin is used for data IO. In 8bit mode, it is an address input
which add one more least significant bit (LSB). In this case
we should shift all adresses by one:
For example 0xaa << 1 = 0x154
"

This patch now is a port of this barebox patch to U-Boot.

Along with the change w.r.t from barebox,
Some flash chips can support multiple bus widths, override the
interface width and limit it to the port width.

Tested on 16-bit Spansion flash on sequoia.
Tested 8-bit flashes like 256M29EW, 512M29EW.
