amd/stoneyridge: Use generic fixed MTRR setup

Add the X86_AMD_FIXED_MTRRS select back to Kconfig.  This got lost
when stoneyridge was converted from a cpu/northbridge/southbridge
implementation to soc/.

Remove the setup from model_15_init.c because this is duplicated

TEST=Boot Kahlee, check steps with HDT
