samus: Combine mainboard patches to build soc/intel/broadwell

Combine four patches dependencies. These will not build
individually, so combine them for coreboot.org upstream.

samus: Move SPD handling to separate file

The code to find the SPD data for the mainboard based on GPIOs
is moved from romstage.c into spd.c.

It relies on the updated pei_data structure from broadwell instead
of the haswell interface.

samus: Move PEI data structure init to separate file

This needs to be executed in both romstage and ramstage
for the different PEI binary stages.

It uses the broadwell interface now instead of haswell.

samus: Convert mainboard to use soc/intel/broadwell

Switch from the haswell cpu/northbridge/southbridge interface
to the soc/intel/broadwell interface.

- Use new headers where appropriate
- Remove code that is now done by the SOC generic code
- Update GPIO map to drop LP specific handling
- Update INT15 handlers, drop all but the boot display hook

samus: Add some code to print basic info from SPD

The handling of LPDDR is a bit messy in Intel platforms.  There
is no traditional SPD so instead one is created by hand from the
provided datasheets.

These have varying (and sometimes unexpected) geometry and it can
be important during bringup to know what configuration is being
passed to the memory training code.

This could in theory be put in a more generic location, but for now
this is the only board with LPDDR3 where I have found it valuable.

BUG=chrome-os-partner:28234
TEST=Build and boot on samus, look for SPD details on the console.
