Timofey Kutergin 6f2d9d7441 target/arm: Fix Privileged Access Never (PAN) for aarch32 
When we implemented the PAN support we theoretically wanted
to support it for both AArch32 and AArch64, but in practice
several bugs made it essentially unusable with an AArch32
guest. Fix all those problems:

    - Use CPSR.PAN to check for PAN state in aarch32 mode
    - throw permission fault during address translation when PAN is
      enabled and kernel tries to access user acessible page
    - ignore SCTLR_XP bit for armv7 and armv8 (conflicts with SCTLR_SPAN).
