Some more DIMM0 related cleanups and deduplication.
- VIA VT8235: Do the shift in smbus_read_byte() as all other chipsets do. - spd.h: Move RC00-RC63 #defines here, they were duplicated in lots of romstage.c files and lots of spd_addr.h files. Don't even bother for those spd_addr.h which aren't even actually used, drop them right away. - Replace various 0x50 hardcoded numbers with DIMM0, 0x51 with DIMM1, and 0xa0 with (DIMM0 << 1) where appropriate. - Various debug.c files: Replace SMBUS_MEM_DEVICE_START with DIMM0, SMBUS_MEM_DEVICE_END with DIMM7, and drop useless SMBUS_MEM_DEVICE_INC. - VIA VX800: Drop unused SMBUS_ADDR_CH* #defines. - VIA VT8623: Do the shift in smbus_read_byte() as all other chipsets do. Then, replace 0xa0 (which now becomes 0x50) with DIMM0. - alix1c/romstage.c, alix2d/romstage.c: Adapt to recent bit shift changes. - Various files: Drop DIMM_SPD_BASE and/or replace it with DIMM0.
