Duplication of config symbols in platform specific Kconfig goes against
common practice. Platform specific values should go in
defconfig. Support for Clearfog SPI boot should be in a dedicated
defconfig, I think.

Same comment on patches #9 and #10.

It might be better to add u-boot,spl-payload-offset property to the
U-Boot specific -u-boot.dtsi file instead.
