[coreboot-gerrit] Change in coreboot[master]: soc/amd/picasso: Don't run dcache_clean_all() in psp_verstage

[Martin Roth (Code Review)]

Hello build bot (Jenkins), Raul Rangel, Furquan Shaikh, Kangheui Won, Rob Barnes, Eric Peers, Aaron Durbin, Kangheui Won, Felix Held,

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

https://review.coreboot.org/c/coreboot/+/43678

to look at the new patch set (#5).

Change subject: soc/amd/picasso: Don't run dcache_clean_all() in psp_verstage

soc/amd/picasso: Don't run dcache_clean_all() in psp_verstage

Because psp_verstage runs in userspace, running the dcache_clean_all
function causes the system to hang.

Adding a soc-specific version of board_reset() allows us to have one
version on the X86 that mirrors the generic version and another copy
for the PSP which skips the dcache_clean_all() function.

BUG=b:161554141
TEST=Run board through a bunch of recovery cycles.
