[PATCH i-g-t 6/6] lib/igt_pm: Convert suspended_time from int to uint64_t

[Rodrigo Vivi <rodrigo.vivi@intel.com>]

Suspended time is in miliseconds printed from u64 variable in kernel.
Convert to a more appropriate variable type.

v2: - Use PRInt macros instead of %ld (Kamil)
    - Explicit time units (Kamil)
    - s/suspend/suspended in the debug msg
