Convert all Intel 440BX boards to Cache-as-RAM (CAR).

 - Add "select CACHE_AS_RAM" in src/cpu/intel/slot_1/Kconfig.

 - Add the following in src/cpu/intel/slot_1/Makefile.inc:
   cpu_incs += $(src)/cpu/intel/car/cache_as_ram.inc

 - Remove "select ROMCC" from all 440BX board Kconfig files.

 - Drop all early_mtrr_init() calls, that's done by CAR code now.

Various small fixes were needed to make it build:

 - Drop do_smbus_recv_byte(), do_smbus_send_byte(), do_smbus_write_byte(),
   those were never called anyways.

 - Remove the "static" from the main() functions in romstage.c files.

 - Always call dump_spd_registers() from the 440BX debug.c, but use
   "#if CONFIG_DEBUG_RAM_SETUP" to only have that code if RAM debugging
   is enabled in menuconfig.

 - Drop all "lib/ramtest.c" #includes and ram_check() calls (even if
   commented out) from romstage.c's, as we've done for most other boards.

 - Add missing #includes or prototypes. Some of the prototypes will be
   removed later when we get rid of the #include'd .c files.

Abuild-tested for all boards, and boot-tested on A-Trend ATC-6220.
