testcases: sanity check TCs get more language for real HW

Add more specifications or qualify some to the sanity check test cases
for them to be ran in real hardware:

 - kernel types (micro vs nano)
 - platforms / arches to exclude / include
 - one that is removed (for the PCI sample) as it cannot be ran
   without extra information
