armv7/snow: get to romstage

This patch does a few things to get us into romstage:
- Add romstage as a stage (a later patch adds it as a binary, which
  is probably wrong). The Makefile magic is complex enough that we
  let it build the XIP file for now, but we no longer use it.

- Replace findstage with loadstage. Loadstage will find a stage,
  load the code to memory, and zero the remaining part of memory.
  Now we can link the romstage to go anywhere!

- Eliminate magic offsets from code/ldscripts and centralize Kconfig
  variables in src/cpu/samsung/exynos5250/Kconfig.

- Tidy up code and serial output
