Remove failover/fallback/normal handling in mainboards'

romstage.c. That's newconfig stuff.

1. In failover_process(), I removed the fallback/normal selection logic
and kept the remaining hardware init in. The if-clauses' conditions are
reverted to match.
Remove #if failover||fallback guard.

2. Change cache_as_ram_main() to first call failover_process, then
real_main unconditionally.

3. Move failover_process's code to the beginning of real_main, remove
failover_process and its call in cache_as_ram_main.

4. Remove cache_as_ram_main, rename real_main to cache_as_ram_main (same
arguments, so no problem with that)
