perf print-events: Fix "perf list" can not display the PMU prefix for some hybrid cache events

Some hybrid hardware cache events are only available on one CPU PMU. For
example, 'L1-dcache-load-misses' is only available on cpu_core.

We have supported in the perf list clearly reporting this info, the
function works fine before but recently the argument "config" in API
is_event_supported() is changed from "u64" to "unsigned int" which
caused a regression, the "perf list" then can not display the PMU prefix
for some hybrid cache events.

For the hybrid systems, the PMU type ID is stored at config[63:32],
define config to "unsigned int" will miss the PMU type ID information,
then the regression happened, the config should be defined as "u64".

Before:
 # ./perf list |grep "Hardware cache event"
