[i945] Add SPD adress mapping
The current code works only with dual channel if Channel 0 uses SPD address
0x50/0x51, while the second channel has to use 0x52/0x53.
For hardware that uses other addresses (like the ThinkPad X60) this means we
get only one module running instead of both.
This patch adds a second parameter to sdram_initialize, which is an array with
2 * DIMM_SOCKETS members. It should contain the SPD addresses for every single
DIMM socket. If NULL is given as the second parameter, the code uses the old
addressing scheme.
