For M-profile, we weren't reporting alignment faults triggered by the generic TCG code correctly to the guest. These get passed into arm_v7m_cpu_do_interrupt() as an EXCP_DATA_ABORT with an A-profile style exception.fsr value of 1. We didn't check for this, and so they fell through into the default of "assume this is an MPU fault" and were reported to the guest as a data access violation MPU fault. Report these alignment faults as UsageFaults which set the UNALIGNED bit in the UFSR.
