tools/intel_bios_reader: Dump PSR block from VBT
Decode the PSR block (9) from VBT. Looks like the same block ID may have
been used for something else in the past, so a version check is also
needed.
The wakeup times part is still up in the air due to the spec not knowing
what it's saying, but let's do something that makes at least some sense
given the VBTs currently out there in the wild.
v2: Actually dump out tp2/3 wakeup time
