soc/amd/picasso: Put transfer buffer into common ld file

Instead of having the same linker layout for the transfer buffer between
the x86 & PSP linker layout scripts, put the common layout into a file
shared between the other linker scripts.

BUG=None
TEST=Boot zork board, verify the buffers are aligned.
BRANCH=Zork
