cpu/amd/agesa/family14/model_14_init.c: create correct MTRR solution

Create the correct MTRR solution based on the physical address space
provided by RESOURCE_ALLOCATOR_V4. Previously CPU initialization did not
account for lost C6 DRAM storage MTRR during postcar frame creation.
The BSP on 2GB has been stripped from UC MTRR covering C6 DRAM and
overlapping with usable DRAM WB MTRR. However this UC MTRR remained on
APs which caused inconsistent MTRRs warning in Linux. Use generic MTRR
function to create correct MTRR solution that propagates to APs. This
also fixes the inconsistent MTRRs warning.

TEST=boot Debian with Linux 4.14 on apu1 2GB
