drm/msm: Add param for userspace to query suspend count
Performance counts, and ALWAYS_ON counters used for capturing GPU
timestamps, lose their state across suspend/resume cycles. Userspace
tooling for performance monitoring needs to be aware of this. For
example, after a suspend userspace needs to recalibrate it's offset
between CPU and GPU time.
