witherspoon-128: Initial commit

Create a machine/witherspoon-128.conf file to model a witherspoon
system with 128MB flash chips.

* New kernel device tree (witherspoon-128.dts).
* Bigger read-write filesystem. Remove the default from the
witherspoon layer (not needed as 6MB is the default) so that the
size value can be overwritten by the witherspoon-128.conf.

- To build this machine:
export MACHINE="witherspoon-128"; \
export BB_ENV_EXTRAWHITE="$BB_ENV_EXTRAWHITE MACHINE"; \
bitbake obmc-phosphor-image

Witherspoon-128 is a system based on Witherspoon but with 128MB
flash chips. Create a device tree for this configuration.
Since this system is just a bringup vehicle, the device tree will
be carried as a patch instead of merging it in upstream linux.
