soc/amd/picasso: Add custom memlayout.ld file
This change copies src/arch/x86/memlayout.ld file to
src/soc/amd/picasso/ and sets MEMLAYOUT_LD_FILE config variable to
point to this newly added file. Unused elements from the memlayout.ld
file are dropped and path to early_dram.ld is updated to include the
one from src/arch/x86.
