soc/amd/picasso: Reboot for recovery if no psp workbuf is found
Instead of halting if the vboot workbuf is not passed to coreboot by the PSP, reset and reboot into recovery mode. This process is made more difficult because if the workbuf isn't available, we can't reboot directly into recovery - the workbuf is needed for that process to be done through the regular calls, and we don't want to go around the vboot API and just write into VBNV directly. To overcome this, we set a CMOS flag, and reset the system. PSP_verstage checks for this flag so it will update VBNV and reset the system after generating the workbuf. BUG=b:152638343 TEST=Simulate the workbuf not being present and verify the reboot process.
