    xen/arm64: io: Handle the abort due to access to stage1 translation table
    
    If the abort was caused due to access to stage1 translation table, Xen
    will try to set the p2m entry (assuming that the Stage 1 translation
    table is in a non MMIO region).
    If there is no such entry found, then Xen will try to map the address as
    a MMIO region (assuming that the Stage 1 translation table is in a
    direct MMIO region).
    
    If that fails as well, then there are the two following scenarios:-
    1. Stage 1 translation table being in an emulated MMIO region - Xen
    can read the region, but it has no way to return the value read to the
    CPU page table walker (which tries to go through the stage1 tables to
    resolve the translation fault).
    
    2. Stage 1 translation table address is invalid.
    
    In both the above scenarios, Xen will forward the abort to the guest.

    xen/arm64: io: Emulate instructions (with invalid ISS) on MMIO region
    
    When an instruction is trapped in Xen due to translation fault, Xen
    checks if the ISS is invalid (for data abort) or it is an instruction
    abort. If so, Xen tries to resolve the translation fault using p2m page
    tables. In case of data abort, Xen will try to map the mmio region to
    the guest (ie tries to emulate the mmio region).
    
    If the ISS is not valid and it is a data abort, then Xen tries to
    decode the instruction. In case of ioreq, Xen  saves the decoding state,
    rn and imm9 to vcpu_io. Whenever the vcpu handles the ioreq successfully,
    it will read the decoding state to determine if the instruction decoded
    was a ldr/str post indexing (ie INSTR_LDR_STR_POSTINDEXING). If so, it
    uses these details to post increment rn.
    
    In case of mmio handler, if the mmio operation was successful, then Xen
    retrives the decoding state, rn and imm9. For state ==
    INSTR_LDR_STR_POSTINDEXING, Xen will update rn.
    
    If there is an error encountered while decoding/executing the instruction,
    Xen will forward the abort to the guest.
    
    Also, the logic to infer the type of instruction has been moved from
    try_handle_mmio() to try_decode_instruction() which is called before.
    try_handle_mmio() is solely responsible for handling the mmio operation.
