arm-ccn: perf: Prevent module unload while PMU is in use


[ Upstream commit c7f5828bf77dcbd61d51f4736c1d5aa35663fbb4 ]

When the PMU driver is built as a module, the perf expects the
pmu->module to be valid, so that the driver is prevented from
being unloaded while it is in use. Fix the CCN pmu driver to
fill in this field.
