Change in coreboot[master]: soc/amd/picasso: Support reset vector in romstage

[Marshall Dawson (Code Review)]

Hello Edward O'Callaghan, Julius Werner, Arthur Heymans, Richard Spiegel, build bot (Jenkins), Martin Roth, Furquan Shaikh, Patrick Georgi,

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/33759

to look at the new patch set (#17).

Change subject: soc/amd/picasso: Support reset vector in romstage
......................................................................

soc/amd/picasso: Support reset vector in romstage

Given that:
 * Picasso comes out of reset with DRAM already functioning
 * The traditional requirements of bootblock and romstage are now
   somewhat minimized
 * The Google vboot solution will run on the PSP and not in a
   separate verstage after bootblock

Add support for a hybrid romstage combining a handful of features
typically in bootblock with the memory discovery in romstage.
