  target/arm: implement armv8 PMUSERENR (user-mode enable bits)

In armv8, this register implements more than a single bit, with
fine-grained enables for read access to event counters, cycles
counters, and write access to the software increment. This change
implements those checks using custom access functions for the relevant
registers.

  target/arm/arm-powerctl: Fix psci info return values

The power state spec section 5.1.5 AFFINITY_INFO defines the
affinity info return values as

  0 ON
  1 OFF
  2 ON_PENDING

I grepped QEMU for power_state to ensure that no assumptions
of OFF=0 were being made.
