tests: qemu: add more tests for ZPCI on S390

1. Test for auto-generating uids while specifying valid fids
2. Test for auto-generating fids while specifying valid uids
3. Test for parse error while specifying a valid fid and an invalid
   uid
4. Test for parse error while specifying two ZPCI devices with same
   uid and fid addresses
5. Test for parse error when both uid and fid are set to zero
6. Test for error while specifying uid and not providing ZPCI
   capability.
