i945/raminit.c: correctly write CLKCFG for 945GC

MHCBAR(CLKCFG) was previously incorrectly written by the
sdram_program_memory_frequency function which required falsely
limiting the max dram frequency for 945GC.

TESTED on Intel d945gclf (memclock 667 and fsb 533) and
Gigabyte ga-945gcm-s2l (memclock 667 and fsb 1067)
