- A new test case for romcc

- Minor romcc fixes
- In smbus_wail_until_done a romcc glitch with || in romcc where it likes
  to run out of registers.  Use | to be explicit that I don't need the short
  circuiting behavior.
- Remove unused #defines from coherent_ht.c
- Update the test in auto.c to 512M
- Add definition of log2 to romcc_io.h
- Implement SPD memory sizing in raminit.c
- Reduce the number of memory devices back 2 to for the SOLO board.
