soc/amd/picasso: Update all PSP and amdfw.rom building

Add Kconfig options and Makefile command line options to generate
the amdfw.rom image.  A new intermediate image is introduced, which
is the initial BIOS image the PSP places into DRAM prior to
releasing the x86 reset.  The amd_biospsp.img is a compressed
version of the romstage.elf program pieces.

Additional details of the PSP items are not public information.  See
NDA document PID #55758.
