soc/amd/picasso: Replace vboot_reboot() in psp_verstage

The vboot_reboot function calls through board_reset() which flushes
the cache before rebooting.  On the PSP, because we're running in
userspace, this causes the system to hang before it can reboot.

Instead, just call the relevant functions of vboot_reboot() directly.

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