The Winbond W25X40 is now being used in the IP02 (and possibly IP04).
Tested and working on the actual device.

This CL is a Winbond SPI flash specific modification following
the same pattern as the earlier Macronix SPI flash specific fix
(http://gerrit.chromium.org/gerrit/7522).
BUG=chromium-os:20105
TEST=manual
. build a Newton bootloader image
. program the image on a Newton device
. restart the device
. at the 'boot>' prompt run the following commands:
setenv xyz 'this is a string'
saveenv
. reboot the device
. at the 'boot>' prompt run 'printenv'
Observe the environment include the new variable.

Make the Winbond flash chip driver support the CONFIG_SPI_FLASH_NO_FAST_READ
option so that it can be used with the ICH SPI controller.
BUG=chrome-os-partner:5829
TEST=With this and other changes, built and vbooted x86-alex and stumpy.

No need for these to be exported as they are only accessed indirectly
via function pointers.

This patch adds a new member to struct spi_flash (u16 sector_size)
and updates the spi flash drivers to start populating it.
This parameter can be used by spi flash commands that need to round
up units of operation to the flash's sector_size.
Having this number in one place also allows duplicated code to be
further collapsed into one common location (such as erase parameter
and the detected message).

All of the spi flash drivers implement the status register polling for
detecting the device ready state, so unify them all in a new helper
function -- spi_flash_wait_ready.

Adds support for Winbond's W25Q64 SPI flash. These devices are used on
(among others) Xilinx' SP601 and SP605 Spartan-6 evaluation boards.
Tested with "sf" commands.

At the moment, the default SPI flash subsystem is quite terse. Errors and
successes both result in a generic message. So move the useful errors and
useful successes to printf output by default.
While we're here, also convert the messages to use print_size().
