After sending a soft reset, the port partner is supposed to respond with an ACCEPT. If ACCEPT is not seen within PD_T_SENDER_RESPONSE, we should try a hard reset. This CL also changes the definition of SOFT_RESET state from an artificial delay state to a state waiting for ACCEPT. With this, we are now just waiting in DISCOVERY state after a reset and therefore we can remove the 30ms artificial delay. BUG=chrome-os-partner:31296 TEST=Along with the next CL to send soft reset on dropped ping, check power doesn't drop when a ping is dropped. TEST=Modify Samus to not send ACCEPT when a SOFT_RESET packet is received. Check that we received HARD_RESET after SOFT_RESET.
