soc/amd/common/psp_verstage: Add UART support to PSP console
This will allow PSP verstage to write logs to the serial console. We
are no longer dependent on using a serial enabled PSP boot loader.
Ideally we would delete this psp printk and use the standard printk.
Since picasso doesn't currently support mapping the UART though, I'll
keep it for now.
BUG=b:215599230
TEST=Boot guybrush and verify PSP logs are output on serial console
