soc/amd/picasso: Add FSP support for including AGESA

AMD has rewritten AGESA (now at v9) for direct inclusion into UEFI
build environments.  Unlike Arch2008 (a.k.a. v5), it can't be built
without additional source, e.g. in EDK II, and has no entry points
for easily building into a legacy BIOS.

AGESA in coreboot now relies on the FSP 2.0 framework published
by Intel and uses the existing fsp2_0 driver.

* Add fsp_memory_init() to romstage.c.  Although Picasso comes out
  of reset with DRAM alive, this call is added to maximize
  compatibility and facilitate internal development.  Future work
  may look at removing it.  AGESA reports the memory map to coreboot
  via HOBs returned from fsp_memory_init().
* Update UPD data and add mainboard calls for this purpose.
* AGESA currently sets up MTRRs, as in most older generations.
  Take ownership back immediately before running ramstage.
* Remove cbmem initialization, as the FSP driver does this step.
* Add chipset_handle_reset() for compatibility.
* Determine the memory map from HOBs passed from AGESA.  Relying
  on the TOM register is misleading when UMA is below 4GB.
