Add a version of samus which supports booting from TPL to SPL and then
to U-Boot. This allows TPL to select from an A or B SPL to support
verified boot with field upgrade.

Only a specific type of SPI flash exists on a board, having board
Kconfig to select the SPI flash seems to make more sense. Other
flash types are not necessary except coreboot, which implies all
available flash drivers there.

This adds basic support for chromebook_samus. This is the 2015 Pixel and
is based on an Intel broadwell platform.
Supported so far are:
- Serial
- SPI flash
- SDRAM init (with MRC cache)
- SATA
- Video (on the internal LCD panel)
- Keyboard
Various less-visible drivers are provided to make the above work (e.g. PCH,
power control and LPC).
The platform requires various binary blobs which are documented in the
README. The major missing feature is USB3 since the existing U-Boot support
does not work correctly with Intel XHCI controllers.
