[v2,0/2] target/xtensa: convert to do_transaction_failed

Message

Hello,

this series converts target/xtensa to use do_transaction_failed callback
and adds a test that checks various types of access to the physically
unmapped addresses.

Changes v1->v2:
- change ldl_phys to address_space_ldl in get_pte and check transaction
  for success;
- add tests that attempt TLB autorefill from the physically unmapped
  addresses.
