[coreboot] [PATCH] __ROMCC__ ifdefs

[Myles Watson]

I think it's time to separate the two meanings of __ROMCC__.  Right now it
is used for:
1. Use simple functions and data types since we don't have RAM
2. Don't use prototypes, romcc doesn't support them.

Right now the patch creates __PRE_RAMINIT__

The name is not the most important part of the patch, and can easily be
changed.

Here are some of the suggestions so far:
__PRE_RAM__
__NO_RAM_YET__
__DURING_RAMINIT__
__USE_NO_RAM__

Unless it was obvious to me which meaning was the correct one for a file, I
added both for now.

Abuild tested.
