Yonghua Huang 61cd6946d0 DM: Remove 'strictio' from UOS bootargs' options
- UOS will boot fail if 'strictio' is enabled ('-e' option), in this
   case (with '-e'), device model will block all PIO accesses whose
   handlers were not registered, after that, device model program will
   exit, hence UOS boot fail.

   actually, such kind of accesses exist, e.g. UOS would program
   PIT registers (port address: 0x43) if hpet is disabled.

 - For debug, we can trap unexpected PIO access in 'default_inout()'
