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
