soc/amd/picasso: Drop the inclusion of entry16.ld and reset16.ld
This change drops the inclusion of entry16.ld and reset16.ld and
instead adds the content of those files directly in memlayout_x86.ld
in amd/picasso. This is done to allow the work for top-aligning
bootblock to happen independent of Picasso layout. Once that is
complete, Picasso layout can be re-evaluated to see if it can make use
of the common bootblock linker file includes.
TEST=Verified that coreboot.rom generated using --timeless is the same
with and without this change for trembyle.
