Duplicate ast_set_def_ext_reg() for individual chip generations
and move call it into per-chip source files. Remove the original
code. AST2100 and AST2500 reuse the function from earlier chips.
AST2600 appears to be incorrect as it uses an older function. Keep
this behavior for now.

Most of struct ast_dramstruct stores hardware state. Some index
values have known or special meaning. The known values are
- 0xffff - Terminal entry in the array
- 0xff00 - Delays the programming for usecs
- 0x0004 - Sets the type of DRAM
Add constants and helper macros for these cases. Also add a helper
macro for testing. Update Gen1 and Gen2+ accordingly.

Declare struct ast_dramstruct in ast_post.h and remove its original
header file.

Move POST code for Gen2+ and Gen1 to separate source files and
hide it in ast_2100_post() ans ast_2000_post(). With P2A
configuration, the POST logic for these chip generations has
been mingled in ast_init_dram_reg(). Hence, handle all generations
in a single change. The split simplifies both cases. Also move
the DRAM init tables for each Gen into the respective source
file. No changes to the overall logic.
