Add the host error monitor with CATERR detection

This adds the host error monitor to monitor GPIOs for errors from
the host.  To start, it can detect and do basic handling of CATERR
assertions:

   1. Detect CATERR assertion
   2. Check power is on
   3. Make sure CATERR is held for at least 2 seconds
   4. Trigger crashdump
   5. Check the CATERR reset setting and power-cycle the system
      if enabled

Tested:
Injected an IERR and confirmed that it was detected and handled
correctly.
