Mark Salter a76b8236ed drivers/perf: xgene_pmu: Fix uninitialized resource struct 
This splat was reported on newer Fedora kernels booting on certain
X-gene based machines:

 xgene-pmu APMC0D83:00: X-Gene PMU version 3
 Unable to handle kernel read from unreadable memory at virtual \
 address 0000000000004006
 ...

 ---[ end trace f08c10566496a703 ]---

This is due to use of an uninitialized local resource struct in the xgene
pmu driver. The thunderx2_pmu driver avoids this by using the resource list
constructed by acpi_dev_get_resources() rather than using a callback from
that function. The callback in the xgene driver didn't fully initialize
the resource. So get rid of the callback and search the resource list as
done by thunderx2.

Fixes: 832c927d11 ("perf: xgene: Add APM X-Gene SoC Performance Monitoring Unit driver")
