[ 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.
Fixes: a33b0daab73a0 ("bus: ARM CCN PMU driver")
