WP4225

I modified the h1iopsusb123 model to add ITMX into the software watchdog switching logic. At the request from Jeff K and Arnaud P, I ammended the WP4225 to include replacing the RMS+DC OSEM parts with the RMS-ONLY OSEM parts. Note these are temporary parts since they have their DC monitors completely removed. After the upgrade to RCG2.8 I will install the new OSEM parts which monitor DC but will not trigger on them.

The install procedure was: kill user models (h1susitmx, h1susitmy, h1susbs), restart the IOP, test the watchdogs to SEI BSC1,2,3, restart the user models. I pressed the DIAG-RESETs to clear latched IPC errors.

I modified the WD MEDM screens accordingly.

This closes out WP4225.
