soc/amd/common: Add code to print AMD STB to boot log

This allows platforms that support AMD's STB (Smart Trace Buffer) to
print the buffer at various points in the boot process.

The STB is roughly a hardware assisted postcode that captures the
time stamp of when the postcode was added to the buffer.  Reading
from the STB clears the data.
