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.
