Connection device_detect and por signal in the model about aib-phy-hardware HOT 2 CLOSED

1. Agree on the output. When in slave mode, device_detect should go from aib PHY to MAC. In the last few months we decided to call this PHY-->MAC signal "m_device_detect". As written this code cannot fully model the slave.

However, the code does not correctly model redundancy for device_detect. As slave, there is only 1 device_detect input buffer. No ANDing or ORing should be done. "For Slaves, the two device_detect bumps should be connected by Slave on-die wiring before the Slave input buffer." As master, there is only 1 device_detect output buffer. "For Masters, the two device_detect bumps should be connected by Master on-die wiring after the Master output buffer." This should be corrected in the model code.

2. POR is similar. There is only one input buffer (Master) or output buffer (Slave). "For Masters, the two por bumps should be connected by Master on-die wiring before the Master input buffer."
   "For Slaves, the two por bumps should be connected by Slave on-die wiring after the Slave output buffer." No ANDing or ORing should be done. This should also be corrected in the model code.
