soc/amd: move non-CAR linker scripts to common directory

AMD family 17h and newer don't use cache as RAM, since the RAM is
already initialized by the PSP when the x86 cores are released from
reset. Therefore they use a different linker script as the rest of the
x86 chips in coreboot do. Since there will be support for newer
generations than Picasso will be added, move those linker scripts from
soc/amd/picasso to soc/amd/common/block/cpu/noncar.

TEST=Timeless build of amd/mandolin and amd/gardenia result in identical
binaries.
