intel cache-as-ram: Move DCACHE_RAM_BASE
Having same memory region set as both WRPROT and WRBACK using MTRRs is undefined behaviour. This could happen if we allow DCACHE_RAM_BASE to be located within CBFS in SPI flash memory and XIP romstage is at the same location. As SPI master by default decodes all of top 16MiB below 4GiB, initial cache-as-ram line fills may have actually read from SPI flash even in the case DCACHE_RAM_BASE was below the nominal 4GiB - ROM_SIZE. There are no reasons to have this as board-specific setting.
