ps8xxx: patch ps8815 A1 chip Device ID
this adds a config option for the ps8815 to override the TCPCI Device
ID field based on the chip hardware revision reported in vendor
defined registers. early ps8815 A1 firmware still reports the same
Device ID value as the A0 chip which makes the two chips
indistinguishable using standard methods. so, we check a vendor
defined register to distinguish the two parts and "patch" the Device
ID. newer ps8815 firmware will correct this, so after we have flushed
out early firmware, we can disable this override feature.
BRANCH=none
BUG=b:158857815,b:159289062
TEST=reflashed FW on ps8815 A0 and A1
