nb/intel/sandybridge: Do not define tables in a header

Header files are supposed to not make allocations from .bss. Builds
fail if said file is included multiple times. To prevent this from
happening, move the definitions to a C file.

Also, rename raminit_patterns to raminit_tables. This is because more
tables that are not patterns will be added here in subsequent changes.

Tested on Asus P8Z77-V LX2, still boots fine.
