mb/asus/am1i-a/buildOpts.c: choose the 1600 MHz RAM frequency
Together with the "AMD_XMP" changes, now this board with Crucial BLT8G3D1869DT1TX0 sticks could run at 1600 MHz CL8 (8-8-9-23) speeds. Earlier only 1333 MHz CL9 (9-9-10-27) has been possible with coreboot.
tRP in "CL-tRCD-tRP-tRAS" gets set 1 point higher by AGESA because of Errata 638. See more info in a BKDG for AMD Family 16h Models 00h-0Fh.
