TCPMv2: Adjust tPSSourceOn to proper valuestabilize-15086.B-main
According to USB Power Delivery Compliance Test Specification,
Revision 1.4 Version 4(TEST.PD.PROT.SRC.10#3). UUT should send Type-C
error recovery within tPSSourceOn.
From the TEST.PD.PROT.SRC.10 test result, UUT sent Type-C Error Recovery
after tPSSourceOn_Max(480ms).The time interval is 0.4896s which is
exceeded the max timing(480ms).
So I pick the value in the middle of 390ms and 480ms.
BUG=b:242119728
